    Pulsed laser clamps voltage when pulsed too fast

    I bought a 50mW laser for use in data communications. I did not plan to use a current driver, just a resistor and mosfet. It's pulsed on/off about 10 times a second at 30mS pulses at 10% duty cycle, so not really on long enough for thermal runaway to be an issue. On the oscilloscope it gets...

    Laser-tag outdoor lasers *pulse vs. class calcs?*

    Hi, I'm currently using OPV302 with a 41x114mm double convex lens to expand the beam. I get ranges in sunlight of 40 yards and 150 yards in the shade. I host games for fun with a variety of equipment I built (I'm an electrical engineer by trade). I would like to figure out how the laser...
