    How can I drive a laser diode at 1MHz for a speed of light experiment?

    Hey guys, I was thinking of building a speed-of-light experiment where I pulsed a laser at around 1MHz (I don't think the duty cycle would matter too much, as long as the on/off is very noticeable) so that I can reflect the pulsing light off a mirror some distance away (maybe 30m), and then I...

    Is LM338 reliable for powering lasers

    I'm quite new to working with lasers although I have experience with electronics in general. I wanted to set up a physics experiment involving a pretty powerful laser (NUBM44-V2) but I can't really buy a commercial laser driver like the Super X-Drive as many have suggested because I live in a...
