Laser diode control without PD
The laser diode seems to be an excellent candidate. However, for the specific wavelength I need (488 nm), diodes with an integrated photodiode cost 10 times more than a diode

Laser Diode Without Driver
Laser Driver FAQ from J Tech Photonics, Inc.
Can''t I just use a lab power supply to hook up my laser diode without a driver? You certainly can hook up a lab power supply to a laser diode and provide a voltage and current to the diode, but you will be

running a laser diode without drive
As long as the voltage source itself is regulated, resistors will be sufficient. So If you''re using batteries, a driver is a better idea, but it will still work with resistors.

Do I need a driver for a single laser?
The laser will not be constantly on for very long, just whenever I''m pressing a limit switch in short bursts. I checked out this question which recommended a driver, but since I''m only using

Running a laser diode without a driver? | Laser Pointer Forums
It is possible but it can burn out your laserdiode. It''s a good idea to get a driver, just so you don''t accidently kill your 45$ laser diode. It can be done with the appropriate current limiting resistor,

Laser diode
Unlike a regular diode, the goal for a laser diode is to recombine all carriers in the I region, and produce light. Thus, laser diodes are fabricated using direct band-gap semiconductors.
