Hi, I have two flat laser diode with 3 pin.One is from 24X dvd burner.Other is from unknown xxX dvd burner.How do I know how much current can handle these two diodes. What is the operating voltage of this flat 3 pin diodes.Can according to their operating voltage to know how much current they...

Hi, I meant to do this type of driver for my new projects.It is very simple and very efficient.With this driver you can regulate output power from 5-95%.So you can adjust power output for laser diode which she need.Just worries me what will happen if the batteries are for example discharged to...

Hi, i think to buy this 808nm,500mw laser diode from ebay.But I can not believe that laser diode of 500mW pull current of 350mA @ 2.2V. Is this appropriate for the current diode or is fake. I ask this because I use red laser diode that consume 500mA of current @ 3.2V for 300mW of power. p.s.I...

Hi,this driver will not be interesting people who can buy special purpose driver for LD.This driver contains parts that are cheap and easily obtainable in the whole world.This driver will be interesting people who have only three battery(3.6v) or only single li-ion(3.7V) and cant find driver...

Hi everyone, my LG GH22NS50 burner(22X) is dead.And I will use red laser diode for my laser pointer.Bud I don't know which is maximal current for its operation.Because it is not standard laser diode package.It has four wires but only two of them are used(pure red LD) because it has separated...

Hi, i have green laser pointer.One day they stop to work.Ir diode was dead.I replace with new IR diode from 16x DVD burner.But they wont work.I only see dimmed red light on output lens.Where is problem?In IR diode or in Nd:YAG crystal.

Hi, I will buy this 24x Drive and use LD for laser pointer. But i dont know which it use laser diode. Do he use standard 5.6mm LD or other nonstandard diode. If someone use AD-5240 for laser pointer can tell my whics is LD inside. Thanx
