Laser Module How can I identify an electronic component?
I am looking at a small laser circuit. Between the power and the laser module, there is a flat component labeled 820. It looks like a resistor, but I'm not sure how to read the value. Could anyone tell me what it might be?
I'd guess it is a resistor with the value of 82 ohms. The 82 are the unit value with the multiplier (10^0) of 1.

75mW green 532nm laser module lighting a match - REAL QUICK
Which battery would be better for supporting a 150mW laser module?
I'm getting my 150 mW laser module tomorrow and I'm looking for a nice power source. I'm trying to decide between a 9V battery and a D battery. If you could post how many hours of life each battery would supply (although I don't know how you would figure that out), that would be great. If you can't figure it out, just tell me which would last longer. Or you could post a power source that's better than either one of the batteries I listed (but remember, I need it to be portable). Thanks.
It depends on the power requirements of the load (the module) how long it has to operate
The mass, the operating conditions…

This book basically gives the over view about The properties of erbiumdoped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise figure. For the amplification of more than 80 channels the DWDM (Dense Wavelength Division Multiplexing) has required CBand (15251565)nm and LBand (15651610)nm EDFA.We show that a flat gain spectrum can be achieved in the range from 1565 to 1610 nm when the EDF length, pump power and pump configuration are appropriately chosen. Special care must be taken when selecting the EDF length.

Acne Treatment - Use Of Lasers
A laser is focused high energy light. The scientific name of LASER is 'Light Amplification by Stimulated Emission of Radiation'. Ordinary light emits photons in all the directions and consists of many wavelengths. Unlike that, laser emits photons in a single direction and consists of a single wavelength. Laser therefore has very high energy and can be focused on any object or in any direction.
Laser is being used to treat many kinds of skin imperfections. Acne is caused by malfunctioning sebaceous glands, excessive population of bacteria P. acnes and excess sebum. Studies have been done to find out how the focused laser energy can treat acne. Let us look at that.
Acne Treatment and diode laser.
Diode laser has been found to be effective in treatment of acne on the back. Diode laser has been also found very effective in treatment of acne on the face. Very good results have been obtained with two or three treatments with diode laser The treatment is well tolerated under local anesthetic and side effects are limited to redness that goes away in some days.
Acne Treatment and pulsed dye laser-
Acne treatment with pulsed dye laser has not been found to be satisfactory in different studies. More studies are required to find out about the effectiveness of pulsed dye laser on acne.
Acne treatment and laser- conclusion
1. Lasers are not yet extensively used to treat acne.
2. More studies are being conducted to find out about the long-term effect of laser treatment.
3. Laser treatment is not covered under insurance in many countries.

High Quality Content by WIKIPEDIA articles Coherent duality in mathematics refers to a number of generalisations of Serre duality, applying to coherent sheaves, in algebraic geometry and complex manifold theory, as well as some aspects of commutative algebra that are part of the local theory. The historical roots of the theory lie in the idea of the adjoint linear system of a linear system of divisors in classical algebraic geometry. This was reexpressed, with the advent of sheaf theory, in a way that made an analogy with Poincare duality more apparent. Then according to a general principle, Grothendiecks relative point of view, the theory of JeanPierre Serre was extended to a proper morphism; Serre duality was recovered as the case of the morphism of a nonsingular projective variety (or complete variety) to a point. The resulting theory is now sometimes called SerreGrothendieckVerdier duality, and is a basic tool in algebraic geometry. A treatment of this theory, Residues and Duality (1966) by Robin Hartshorne, became an accessible reference. One concrete spinoff was the Grothendieck residue.

A port was introduced in 1983 as the first Unixlike system for IBM PC compatible computers. Coherent was able to run on most Intelbased PCs with Intel 8088, 286, 386, and 486 processors. Coherent version 3 for Intelbased PCs required at least a 286, Coherent version 4 for Intelbased PCs required at least a 386. Like a true Unix, Coherent was able to multitask and support multiple users. From version 4 on Coherent also had support for X11 and MGR windowing systems.

High Quality Content by WIKIPEDIA articles A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser beams set to music, or may accompany another form of entertainment, typically a dance concert or other musical performance. Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and is often used as an effect. Sometimes the beams are bounced to different positions with mirrors to create laser sculptures.

MPSK (Mary Phase Shift Keying) modulation is used in a wide variety of communications systems. Use of MPSK is widespread in wireless networking standards, telephony links, cellular telephony, digital television standards, fiberoptic communications, mobile communications, and military communications. Systems which use MPSK can be found worldwide in terrestrial, satellite, and deepspace applications. Despite the ubiquitous use of MPSK, some coherent MPSK receiver structures have evolved very little since the Costas loop was invented in the 1950s. In this groundbreaking book, new structures for use within coherent MPSK receivers are presented. These include carrier lock detectors, carrier phase detectors, and SNR (Signal to Noise Ratio) estimators. The aforementioned structures are thoroughly analyzed and compared to previously available structures and it is shown that they have significant performance advantages and have immediate applications for use in MPSK systems. Therefore, this book is indispensable to any scientist or engineer who is tasked with the research or development of MPSK communications systems.

In Coherent Stress Testing: A Bayesian Approach, industry expert Riccardo Rebonato presents a groundbreaking new approach to this important but often undervalued part of the risk management toolkit. Based on the author`s extensive work, research and presentations in the area, the book fills a gap in quantitative risk management by introducing a new and very intuitively appealing approach to stress testing based on expert judgement and Bayesian networks. It constitutes a radical departure from the traditional statistical methodologies based on Economic Capital or Extreme-Value-Theory approaches. The book is split into four parts. Part I looks at stress testing and at its role in modern risk management. It discusses the distinctions between risk and uncertainty, the different types of probability that are used in risk management today and for which tasks they are best used. Stress testing is positioned as a bridge between the statistical areas where VaR can be effective and the domain of total Keynesian uncertainty. Part II lays down the quantitative foundations for the concepts described in the rest of the book. Part III takes readers through the application of the tools discussed in part II, and introduces two different systematic approaches to obtaining a coherent stress testing output that can satisfy the needs of industry users and regulators. In part IV the author addresses more practical questions such as embedding the suggestions of the book into a viable governance structure.

A freeelectron laser, or FEL, is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses some very different operating principles to form the beam. Unlike gas, liquid, or solidstate lasers such as diode lasers, in which electrons are excited in bound atomic or molecular states, FELs use a relativistic electron beam as the lasing medium which moves freely through a magnetic structure, hence the term free electron. The freeelectron laser has the widest frequency range of any laser type, and can be widely tunable, currently ranging in wavelength from microwaves, through terahertz radiation and infrared, to the visible spectrum, to ultraviolet, to Xrays. Free Electron Lasers were invented by John Madey in 1976 at Stanford University. The work emanates from research done by Hans Motz who proposed the wiggler magnetic configuration which is at the heart of a free electron laser. Madey used a 24 MeV electron beam and 5 m long wiggler to amplify a signal. Soon afterward, other laboratories with accelerators started developing such lasers.

Types Of Lasers Used In Medical Procedures
The types of lasers used in medical procedures come in a variety of intensities to suit a number of different purposes. Below is some basic information regarding the various types and uses of medical lasers.
Cold Lasers
Low level laser therapy is an up and coming alternative medical treatment. Low level lasers, also called cold lasers, emit a mild beam that can be quite helpful in a number of noninvasive procedures. It's been found that certain wavelengths of light at certain intensities can have a beneficial effect on tissue regeneration, inflammation and pain. The lasers are used in mild, non-surgical procedures, including a replacement for liposuction.
Aesthetic lasers use low level laser technology to biostimulate natural detoxification processes, which results in fat loss. They can also be used to increase the body's ability to heal, relieve pain and reduce swelling. Cold, low level lasers have proved effective in alleviating chronic pain, soft tissue injury, and wound healing. They have also been found to relieve joint and muscle pain as well.
Carbon Dioxide Laser
This laser is a highly precise, bloodless light scalpel used for incising and excising tissue while sealing blood vessels. The carbon dioxide laser is probably what most people think of when they picture laser surgery. This laser is strictly for going in and cutting, yet it creates an incision that doesn't bleed, as the light stops the bleeding on contact. It's far more exact with fewer complications than the traditional scalpel.
Argon Laser
This laser produces a blue-green, coherent light at a variety of different wavelengths, 80% of which occur between 488 and 515 nm. This laser was actually first used in eye surgery to treat diabetic retinopathy without damaging the clear anterior parts of the eye. The laser is now widely used for blood vessel coagulation but can also perform slow, thermal tissue destruction at increased power levels.
Neodymium-YAG Laser
This laser is used both for tissue destruction and to control the flow of normal to abnormal blood vessels. Producing infrared coherent light at a wavelength of 1060 nm, this laser's beam is deeply absorbed in the tissue. It is quite useful in gastrointestinal and urologic pathology.

This month, a new device out of MIT Media Lab's Camera Culture group utilizes one of the most rapidly proliferating technologies in the developing world – mobile phones – to make the diagnostic process of refractive errors of the eye, including nearsightedness, farsightedness, astigmatism, and age-related vision loss, both affordable and accessible to underprivileged populations. NETRA (Near-Eye Tool for Refractive Assessment) uses a phone's LCD display and intelligent software to administer a quick, effective and accurate vision test that patients can perform at home. NETRA means "eye" in Sanskrit, and stands for Near Eye Tool for Refractive Assessment.
Devices using the Shack-Hartmann sensor shine a laser into the eye of the patient, are quite expensive, and require a trained professional operator. The NETRA system uses the dual of a Shack-Hartman sensor, and replaces the laser with simple user interaction. This significantly reduces the cost of the device and makes it appropriate for self-evaluation, while still providing comparable data. As of now, the NETRA can only be used with a high-resolution cell phone display, but Raskar said he hoped that "though not everyone can buy such a phone, a village shopkeeper may have one and it can be used to provide eye care to everyone in the village". NETRA current prototype cost less than USD 2.00 using laser-cut, hand-assembled parts. Since the device essentially made of plastic, this cost will rapidly reduce to just a few cents if mass produced.
The micro-lens array in front of the LCD essentially creates a 4D display. A traditional 3D display presents a slightly-different view to a person's left eye and their right eye. With NETRA, we present different views through different parts of the same eye. If the eye is free from aberrations, it focuses clearly and these disparate views overlap perfectly. But far and near-sighted users have to press a few buttons to make that happen. The numbers of tweaks it takes for them to hit that ideal alignment reveals the correction they need to focus clearly. NETRA relies on a programmable high resolution display to generate patterns at arbitrary depths. The resolution of cheap LCDs found on popular phones recently took a giant leap. For instance, while current LCD monitors support about 90 Dots-Per-Inch (DPI), the Nexus One and the new iPhone 4G supports 250 and 326 DPI respectively. The display resolution defines the resolution of the NETRA device in diopters, and for it to be usable as an optometry solution, reasonably high resolution displays are required. The resolution is 0.4 diopters using the Nexus One device (focal length 30mm, pinhole pitch 3mm, lens-eye distance 15mm). The Apple iPhone 4G, with the new Retina Display should achieve a resolution of approximately 0.28 diopters (focal length 30mm, hole pitch 3mm, lens-eye distance 15mm).
For measuring eye correction, the average absolute errors from the known prescriptions were under 0.5 diopter (σ = 0.2) for both cylindrical and spherical powers. The average absolute error of our estimates of the cylindrical axis was under 6 degrees. Optometrists typically prescribe in multiples of 0.25 diopter, and 10 degrees axis.
At its most basic application, the NETRA test consists of a small plastic device clipped onto the phone's screen. The patient looks into a tiny lens, presses the phone's arrow keys to make a set of parallel green and red lines overlap, bringing view into sharp focus, and repeats this eight times for each eye as the lines appear at different angles. Software loaded onto the phone then provides the precise prescription data. It may sound laborious, but the entire process takes under two minutes.
What makes NETRA particularly promising is its reliance on a cheap and increasingly widespread device. With more than half of all households in the developing world owning a cellular phone, growing at six times the adoption rate of the developed world according to UN statistics, and nearly one billion people worldwide in need of corrective eyewear, NETRA offers a brilliant marriage of need and convenience.
