Thanks to irresponsible little sh!ts like that, anyone else who uses a laser in public is automatically assumed to be a danger.
Why is it that there are always a few jerk-offs that give responsible hobbyists a bad name?
Whether it's the insufferable moron who insists on leaving his [insert dangerous device] collection where his kids can get at them, or schmucks like this guy who get off on using their own potentially dangerous items without any thought to the safety of others, there's always a very visible minority that ruins it for everyone else.
That is f'ed up beyond belief. He holds it RIGHT ON those people at point blank range. I actually feel angry watching that video. A beam like that seems completely normal in a nightclub environment. Those poor folks have no idea the damage it's doing.
I am so tempted to report this to the police. I bet Google would give up his IP address for sure given the circumstances. I wonder if there's anyone I could report it to...
that's not 200mW, the laser go intothe camera many times, plus in both videos he shines it into everyone's face, if that was 200mW then the people around is idiot, even I dont know nothing aobut lasers, a guy comes shines a bright green beam in mey eye and then i cant see nothing and I use to other eye to seek and destroy -.-
So. Check this out.
It's a video of a guy shining a 2watt IR laser around a big city (Tokyo?) lighting up apartment rooms, and flashing signs and cars. http://v.youku.com/v_show/id_XNzcxODAyNDA
WTF? How many people did this guy flash with IR (808nm) and they didn't even know it? I wonder if he caused permanent damage to some unsuspecting unfortunate people. Is this an example of laser irresponsibility?
It is a very irresponsible thing to do, especially what he is doing close range on the street.
When he shines at the other tall buildings, it's not as dangerous since the divergence looks like it is so big, the beam is over a foot in diameter when hitting the windows. 2 watts at a foot wide is about as bad as 2 mW a centimeter wide, about the edge on what is generally considered safe.
If IR is more dangrous is general is hard to say. Visible light attrackts attention and makes people look directly at the source making chances of injury greater, but it also triggers the blink relects offering some protection.
Chances are that all of us are exposed to IR laser beams once in a while though - they find application in things like rangefinders, but also laser guns the police use to write speeding tickets. Especially the latter tend to point you straight in the face.
