This laser pointer works based on optical amplification process and on the stimulated emission of electromagnetic radiation. Building a laser driver circuit? Stack Exchange in a driver circuit for a laser I need to regulate not only voltage but current as well. For a laser diode, you generally want to drive it with a constant current source. However you should design the source to have a maximum output voltage consistent with the laser's maximum ratings to avoid damaging the laser during power up, power down, or in case of a current control failure. LASER DIODE DRIVER BASICS – Wavelength Electronics Limit Circuit:  This section of the laser diode driver is key to protect the laser diode. The user sets the limit current based on the operating parameters of the laser diode (typically well below damage threshold). An Active Current Limit will shut off the laser diode current if the control system drive exceeds this current limit setting. Laser Drivers Laser Controllers Laser Diode Drivers ...

How to Build a Laser (general Guide): 8 Steps How to Build a Laser (general Guide): Here you have 2 options: either to get a DVD drive for pc and extract only the diode assembly (aka sled). or buy just the laser assembly from the internet. You can get old DVD RW drives on ebay for >15usd, or just look around and ask friends if they don't have some old unused drives. Laser driver circuit Electrical Engineering Stack Exchange I like to build a laser pointer driver circuit that I can drive from an 8 bit uC. However, I like to get light output fairly constant. This requires for me to look at the photo detector (these lasers come with 3 pins, gnd, laser cathode, pd cathode) current and adjust laser input current to stabilize light output. Homemade Laser Driver with LM317 Langeder.org Blog Im new to all this stuff so could you tell me the components for testing a red laser driver circuit?
