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.

Simulation of Ingan Blue Laser Diode $172.06 In this book, the design of InGaN LDs structures including multi quantum wells (MQWs) active region device are described and investigated by integrated system engineering technology computer aided design (ISE TCAD) device simulator. The parameters of the LDs structures are varied and optimized for high performance. This optimization study involves aspects such as thickness of active region, doping, thickness of stopper layer region, thickness of quantum wells and quantum barriers, number of quantum wells and several approaches to improve and achieve high efficiency, low threshold current and high output power of InGaN LDs. The basic LDs structures treated here are FabryPerot type InGaN double heterostructure (DH), separate confinement heterostructure (SCH) and multi quantum wells (MQWs).High performance LD has been obtained by using multi quantum wells incorporated with the optimized parameters. The lowest threshold current, higher external quantum efficiency and characteristic temperature are obtained when the number of InGaN well layers is two, at our laser emission wavelength of 415 nm, which is related to the problem of inhomogeneous carrier.

Diode Laser and Naocl as Root Canal Disinfectant $111.53 Enterococc faecalis considered to be the mostresistant bacteria of the root canal, in the presentstudy we used two types of root canal disinfectant toshow their effect on this type of bacteria, the firstis the diode laser and the second NaOCl solution withspecial concentrations and times. the study conductedon human decoronated extracted teeth, adjusted with13mm root length, filled with a suspension of E.faecalis, Samples were divided into 14 groups eachgroup consisted of 10 prepared roots, sixty sampleswere irrigated with NaOCl solution at differentconcentrations (0.5, 2.5 and 5.25) at twoselected times (2 minutes and 5 minutes) for eachconcentration.Sixty samples were irradiated at different powers (2W, 2.5W and 3W); each power at thetotal irradiation time 30 and 60 seconds. Whencomparison was made between NaOCl irrigant and diodelaser in a combination among differentconcentrations, powers and times the result showedthat 5.25 NaOCl at both 2 minutes and 5 minutes hadthe highest antimicrobial effect with no significantdifferences from 3W laser / 10 sec (6 cycles) butsignificantly different from 3W / 5 sec (6 cycles).

The many uses of a green beam laser pointer

The green beam laser pointer is extremely useful at pinpointing objects in a distance. It is an extremely effective pointing device for teachers, architects and engineers. The effectiveness of the green beam laser pointer over standard flashlight devices is the obstructive view and the large distance.

Many different 200mw green laser pointer pen models have been used for other purposes such as light shows and as flashlights. These devices put out a different light pattern than standard green beam laser pointer pens. The 200mw green laser pointer pen is an effective lighting device for indoor areas. It has an intense beam which can be seen against any indoor light source. It creates a prominent light dot which can be easily followed by the eye.

Astronomy green laser pointer pens are used for projecting the point over a great distance. The astronomy green laser pointer can accurately point out stars and constellations within the night sky. It is often used for marking distances and points for calculations and measurement. Many architects and engineers use the green beam laser pointer to point out structural defects that are hazardous.  

The green beam laser pointer comes in a variety of different power outputs. The highest power rating beam is the 700mw power source. Green beam laser pointer pens can utilize rechargeable batteries. Many laser pen manufacturers produce tailor made batteries that can be recharged over an extended period of time. Most batteries produced in this manner are often capable of providing a 3.7volt output. Using compatible batteries with a green beam laser pointer can increase the life span of the laser pointer diode. Therefore it is recommended that both products be purchased and used together. Rechargeable laser pointer pen batteries can be charged from any charger model regardless of brand.

Green beam laser pointer pens are enclosed within an aluminum case that is water proof and durable. The casing prevents corrosion and leakage of liquid substances. The case ensures that shock damage cannot occur to the interior mechanism. Hardened stainless steel cases are also provided with more heavy duty green beam laser pointer pen models. These cases are water proof to a depth of 25 meters and are made for rugged outdoor usage.
