Green Laser Pointer II $69.99 Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. Features of this unit include: Very bright green laser at 532 nm wavelength Output power of Range of approximately 9,000 ft (2600 m) in darkness 1.1 mm beam diameter at source Momentary push button switch Solid, heavy duty construction Constant wave output (as opposed to pulse output) Takes 2 "AAA" batteries (not included) Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives Dimensions: 5.6" x .5" dia 90-day warranty Available in Black or Silver color Interested in quantity discounts or custom logo imprinting? More info here. Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely.

Study of Laser Diode and Edfa $111.53 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.

Beginners Guide to Laser Engraving

With so many options on laser marking systems available today it is not surprising that many people get confused with which is the most suitable to their application. Many people don’t even know that the term “laser”, is actually an acronym – Light amplification by stimulated emission of radiation – which explains the process by which a laser beam is created. The basic theory of this is simple. A gain medium (the material that is used to create the laser light), is excited using either light or electrical energy to generate photons (the laser light). All of this is happening in a closed cavity, with a completely reflective mirror at one end, and a semi reflective one at the other. When the light bouncing around inside gains enough energy, it escapes through the semi-reflective mirror.

These high energy photons are then focused to a small spot (much like you did at school when you used a magnifying glass to focus the sunlight to burn things!). If it is a vector laser, this beam is deflected and directed using a pair of mirrors (X and Y deflection). This guide will help you understand the capabilities of the 3 most common lasers available in the market today:

• A CO2 laser: the Carbon Dioxide gas sealed inside the laser (along with some other gases – most commonly nitrogen, and helium) is pumped (excited / heated up) using electrical energy (DC, AC or RF) which creates the stream of photons.
• An Nd:YAG laser: the neodymium-doped yttrium aluminium garnet (Nd:Y3Al5O12) is pumped using a lamp or diode to emit the stream of photons.
• A Fiber laser: a glass fiber doped with a rare earth ion – most commonly ytterbium (Yb3+) – is diode pumped and the photons generated are reflected down the fiber towards the deflecting mirrors.

What are the differences?

The basic differences between the nd:YAG / Fiber and CO2 Lasers is the wavelength of the beam that it produces. The light emitted from a laser sits within the Invisible Light - Infrared region of the electromagnetic spectrum.

The light of the YAG and fiber lasers are emitted at a wavelength that is precisely 10 times smaller (1.064 µm) than that of a CO2 laser(10.6 µm).

This smaller wavelength also means that if the Nd:YAG/Fiber and CO2 lasers were used in the same application (with the same set-up). The Nd:YAG/Fiber would have a much smaller spot size and consequently, mark with a better resolution.

What difference does this make?

These wavelengths determine which laser should be used for each application, as the material to be marked will have different absorption capabilities (of the light at different wavelengths). If a material can absorb the light, then it can be affected by it.

Which one should I use for metal?

Most metals are highly reflective and therefore, an Nd:YAG or Fiber laser would be most suited.The wavelength being much shorter means there will be less reflection of the beam on the surface, therefore less loss of energy and consequently easier working of the metal. The metal absorbs more of the light energy that changes its physical properties.

Which one should I use for non – metal?

Organic materials such as wood, acrylics, plastics, fabrics, and transparent objects are better suited to the CO2 as the wavelength is longer and has more latitude. However the Nd:YAG and Fiber lasers can be used to mark some non-metals too. But if the object is transparent (eg. glass) then the YAG / Fiber laser light will pass through it without marking it.

Laser markers can produce alpha-numeric characters, bar codes, serial numbers, logo's, artwork and other graphic images using a non-contact thermal process.

Is there an easy way of knowing which would be most suitable?

Ideally, a sample of the material would have to be tested , but generally think of CO2 for Organic and YAG and its derivatives (Fiber, nd:YAG .. etc) for Non Organic materials.

Okay, I have decided to go for either an nd:YAG or Fiber laser, what are the differences??

• The nd:YAG uses a lamp or a diode pack (array) to excite the gain medium - these require more electrical power and wear out (and are very costly to replace). They, also produce a lot of heat and require more heat dissipation (some water cooled – most now use heat-sinks and thermo-electric cooling systems)
• The fiber lasers use many single emitter diodes that are cheaper to run, and will last the lifetime of the fiber. The mean time before failure is greater than 50,000hrs
• The fiber laser is more stable at all power levels.
• The light source with a fiber is completely sealed all the way to the marking head. This stops dust and particle contamination and enables longer working distances between the control unit and marking head. It also reduces any leakage and therefore increases the efficiency of the laser beam.
• The fiber laser “boots up” a lot quicker.
• The fiber laser has less replacement parts (such as resonator mirrors, crystals, fluids and filters)
