Dvd diode driver

It is the basic laser diode driver source of light. When the actual laser diode current is flowing, electrons and holes will travel towards the P-N junction. Note that electrons are negatively charged while holes are positively charged. The combination of the holes and electrons .  · Took an old Rewritable DVD drive and extracted the red laser diode to use in a future project. Stay tuned for the next video and feel free to ask questions i.  · Hi, I bought a few cheap high speed DVD burner drives. I will be harvesting the laser diodes from them for use in compact portable laser modules. Does anyone have a good idea for a LD driver circut for these? I would like to use a single LiPo V cell, and I would like to have a regulated constant current source for the laser diodes.

It should be mA. In CD-ROM and DVD-ROM you could also find IR driver, DVD laser writer diode will be a little more powerfull than the CD one. Laser diode usually has three pins, one is the common ground, laser and photodiode cathode (-), one the laser diode anode (+), the other is the monitor photodiode anode (+). Warning! Laser diodes from DVD-RW drive are emitting visible and invisible laser radiation and they are extremely dangerous! Their light can permanently damage the eyes. You must never look into the working diode even without the lens or point it on a reflective surface. Laser beam can cause burns or fire. This is usually a Class IIIb laser. Took an old Rewritable DVD drive and extracted the red laser diode to use in a future project. Stay tuned for the next video and feel free to ask questions i.
