I'm a new member. I've been reading this forum for over a month before joining, mainly to decide if this was something I wanted to get into and there's a ton of helpful information on here. Thank you for all the previous members contributing. So I decided to get a cheap 405nm laser module from Dino Direct during their holiday "deals". Here's the one I ordered :50mW 405nm Focused Line Violet Blue Laser Module M405L50-3-1670 - DinoDirect.com
First of all, based on other contributors postings, I do not believe this laser is up to the 50mw rating it claims. At any rate, it was cheap so I figured when just starting out it would be worth it to get my feet wet. I'm curious about the operating voltage listed as: 3-6V, 7-15V. I've powered it with 4 double AA's in parallel. But it seems to be underpowered and it drains the batteries super fast. I'm just curious what other ideas might be in powering this. Should I trust the wide spread of 3-15V? Please share your thoughts. Thanks in advance.
