Hello,
I'd like to start by saying thanks to everyone's post on this forum as it has been a great resource to me in my first laser build. Since the creation of my unknown strength laser I have become terrified of it. I had built a laser with a 9mm 445nm diode driven by as 2.2amp driver in a S4 host with a single element lens. I'm guessing it is in the upper 2watt range. Now I know your reading this and saying why did this guy start off with such a high powered laser. Well, here's the answer my reef aquarium. It all started because I had seen some videos of guys killing aptasias (an aquarium pest) with lasers. So I did my home work and bought a pair of OD4+ eagle pair safety glasses and started zapping away. It works great and is very cool however, I've become concerned about eye damage. So here it goes I have a few questions for you. 1) Can burning with the laser mentioned above while wearing the eagle pair glasses result in eye damage when staring at the dot at relative close range for a minute or less?
2) Is it ever safe to look at the beam of this laser in the night sky with no eye protection?
I realize this is a lot of laser and i think I'm getting paranoid that I'm damaging my eyes even with decent glasses.
