So I've been working on my very first laser build. I'm building it out of this diode HighTechDealZ - 405nm PHR805T Blu Ray Laser Diode in Aixiz Module I recently got done soldering leads to the pins and I took tons of caution. Surrounded the module in aluminum as a heatsink and was very...

I did mean 125mA, my bad. But thank you for the redirection, I have everything I need to know now.

Thank you all so very much. This community is great and I'm grateful for the feedback! I believe this is my last question. If I were to run a current of 100mA to the diode with the module shown in the link I posted earlier, will I require a heat sink or does the module satisfy the needs for...

One more question. Do the Li-ion batteries have a holder? I can't seem to find one (maybe I suck at looking) and the host I'm using isn't a pen or flashlight host so I can't use a spring. Any other way you would recommend wiring batteries without a holder?

Oh, my bad. I meant 125mA, thank you for understanding. Here is the page I purchased the diode from. HighTechDealZ - 405nm PHR805T Blu Ray Laser Diode in Aixiz Module It labeled it as 120mA current, but if you're all recommending lower than perhaps I'll just wire two 10 Ohms in series. Thank...

Hi there guys! So I'll start by saying I'm very new to building lasers, so this forum included, and I would love to be apart of it. I'll appreciate any bit of help I can get or even "critical" advice. So I'm starting my first build with a custom made driver, I'm just using the basic LM317...
