Hello,
I want to share this here both as a question and as an alarm to anyone reading this who uses or will use lasers.
When I went on to buy my first blue 1W 445 nm laser, it was off an internet post. The guy selling it proceeded to show it to me, us both unprotected, in a bright sunlight...
I figured out I am wondering. How is it possible for blue lasers to be used in laser shows (even when diffused, thus much less powerful), if the blue light in any strength is considered to possibly cause photochemical damage to the eye?
Hello,
I randomly saw this happening at a fair in Bulgaria. The laser is scanning right in the eyes of the buyers from thus stand as well as kids are playing among the figures. Is this a safe situation?
I have no other good place to post this question, so please bear with me. I was recklessly shown how a 1W 445 nm laser burns paper, lights a match and melts a plastic cap. The demonstration happened outside. I did not know all that I know now about lasers at the time of the event. I looked...

What is the case with blue (445)...
Hello guys, my third post here, as I am researching the topic of laser safety. I stumbled upon THIS video (it's not mine and I do not know that person):
And I am in AWE. How can someone be THAT irresponsible? But probably the more interesting question - are lasers THAT dangerous of someone...
Hello,
I just bought my first blue laser. Not knowing enough about it, I fell a “victim” to the seller (got it second hand) as he was demoing it for me prior to purchase. He happily shown me how it burns a matchstick, white paper (!) and blue plastic cap. This happened outside in pure daylight...
