    Diode Housing Heat Dissipation

    Thanks for your findings pierce :) I wonder at what power acrylic lens would melt and you would need AR coated glass lens?

    Diode Housing Heat Dissipation

    Ooh I see. Yeah I'll be sure to put it in a heatsink, thanks for the help :D Sorry about all the noob questions haha I just got started into lasers

    Diode Housing Heat Dissipation

    I see thanks for that :) What do you think the power limit is for brass housings though? Also I live in Australia so the shipping is a bit pricey for me :(

    Diode Housing Heat Dissipation

    Hi everyone, I've got these diode housings and I'm not sure what kind of metal they're made of (the description just says metal). I'm guessing it might be iron or steel though I'm not sure. Does anyone have any ideas? Anyway I was wondering if there was a rule of thumb of choosing a housing...

    Faulty Laser Diode? Or did I fry it...

    Well I tried making an RC plane but I think I broke the ESC... so I'm just reusing the battery for lasers lol Though when I have time I might try again...

    Faulty Laser Diode? Or did I fry it...

    Oh my I feel so stupid lol Thanks so much for the help :D Just wondering do you think I should increase the resistance a bit more in case the tolerance is outside the acceptable limits 🤔 EDIT: Nevermind, just checked it with a mulitimeter, seems to be within the limits Thanks everyone for your...

    Faulty Laser Diode? Or did I fry it...

    I see, but I'm fairly certain it's wayy too dim. It can barely illuminate my hand 10cm away So I'm using this circuit powered by a Lipo battery. I connected Iout to the LD anode, and ground to the common pin of the diode. Instead of the 10 ohm resistor I'm using 40 ohms. Here's some photos...

    Faulty Laser Diode? Or did I fry it...

    Hey everyone, Sorry if there was already a post about this, I did use the search function but didn't find much stuff. Anyways I bought two SLD3134VL 20mw 405nm diodes from eBay and they arrived in plastic packaging (not even in antiESD bags). So I tried out one of the diodes by using a constant...

    Has anyone tried this housing?

    Thanks so much for the reply :D Thanks for the tips I'll try it out and see how it goes. When I test it I'll post the results here

    Has anyone tried this housing?

    Hi everyone :) I'm new here and I just started getting into lasers. I'm trying to build my first laser using an SLD3134VL 405nm 20mW laser diode. For the diode housing I found this on Aliexpress: (sorry I can't post links yet) "10x Focusable 1230 Metal Housing w Lens for TO-18 5.6mm Laser Diode...
