Burning Laser Diode Will this laser diode burn anything?
I picked up a red 635 nm laser diode, and I am wondering if, when hooked up properly, it could burn anything.
It really depends on the diode. You should look at what the diode's power is rated at. If it is above 5mW, it can burn you retina and cause permanent eye damage. If it is 500mW or above, it might be able to burn a hole in a piece of paper if you do it correctly (and blind you 100 times faster than a 5mW laser). If it is rated to 1kW, you might be able to use it as a weapon... but it will not be rated that high.
TZ is quite wrong in his/her answer. Though red is the lowest of the visible wavelengths, and thus has less energy per photon, the energy per photon is irrelevant. If you want to burn stuff you care only about how many photons. So a red laser that gives off twice as many photons will burn things better than any other visible laser that gives off less light. The fact that TZ brought up microwaves as a cooking wavelength is a rather comical emphasis of this point, since microwaves have significantly longer wavelengths than visible light (so by TZ's logic they should NOT cook anything... yes TZ was wrong about how long microwaves are), though they do cook things because they are high power. Actually, they only cook water, because they have a resonance in the molecular vibrational spectrum of water that allows them to cook water without cooking other things. TZ was also wrong in saying that you should look at the power supply for your diode. The power supply is much less important than the power rating of the diode. If you drive a 5mW diode with a 5W power supply, you will simply burn it out. Diodes are made to only work in a limited range of powers, and your power supply, as long as it is sufficient to drive the diode, will only allow the diode to run at the diode's rated power.
Laser Diode Microsystems provides the reader with the basic knowledge and understanding required for using semiconductor laser diodes in optical microsystems and microoptical electromechanic systems. This tutorial addresses the fundamentals of semiconductor laser operation and design, coupled with an overview of the types of laser diodes suitable for use in Microsystems, along with their distinguishing characteristics. Emphasis is placed on laser diode characterization and measurement as well as the assembly techniques and optical accessories required for incorporation of semiconductor lasers into complex microsystems. Equipped with typical results and calculation examples, this handon text helps readers to develop a feel for how to choose a laser diode, characterize it and incorporate it into a microsystem.

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.

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.

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).

DVD 24X Burning laser diode demos and uses.
How powerful is diode from a 8x speed DVD burner driver?
Okay i am beginning to make a burning laser. I have a question, can i use a 5mw, regular laser pointer, and take it off and attach the diode from the dvd drive to the laser pointer? If i can how powerful could the laser be? It is a class 1 laser product and it is: DVD writer model TS-L633.
Please need some information on this, not no comments how I should have experience or anything like that. Cause i posted something similar to this, i checked out many videos, non of them state that a regular laser pointer diode can be switched with a dvd burner diode.
What I am using is Leawo Free DVD Creator.It is easy to use, and it can convert videos to dvd in several steps.You can find Leawo Free DVD Creator here:
