Hey everyone. I'm new to this forum, and i need some help. I built a roughly 1.2 watt 445nm laser a few months ago. It was my first homemade laser as well as my most powerful. I really enjoy using it for burning and just for looking at in the dark. Last night i was using it and it suddenly became very dull to the point where it was hard to see in the dark. Now i dont know too much about laser technology as i am fairly new to this, but i tried charging up the batteries and using them in it and another laser and it was obvious that was not the problem. I am worried that the diode is broken which would suck because i dont have the money for another one and I probably dont have the tools needed to fix it. Thanks in advanced and i look forward to your help.
