    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 might actually take you up on that offer, I'll just have to discuss with my partner first

    Is LM338 reliable for powering lasers

    This does sound cheaper than other shipping options, but is there any reason the drivers can't be mailed in an envelope to cut the costs down to under $5? Thank you for your kind offer, but the SXD itself might still be pushing the budget a bit so I will have to think about it. I did more...

    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...
