I've just received a [http://www.wickedlasers.com/lasers/Executive_Series-55-3.html 15mW green laser] from WickedLaser, and I'm terribly afraid of the safety guidelines to not harm myself and others, could you explain a bit more about it?
 +
 
 +
* is it safe to use indoor?
 +
* laser point is really bright when nearer than 5 meters, is it dangerous?
 +
* which is the best laser to use? links to laser shop
 +
* Laser Tag from GRL is perfect with its target far above heads, how to deal with a crowd when using laser?
 +
 
 +
Well... I think we used a 15, 20 or 30mW laser - don't know exactly. We followed two security guidelines and so far nobody got hurt:
 +
 
 +
# Don't point at people. DON'T! NEVAR! EVAR!
 +
# Don't point at stuff that might reflect the laser. You can't know where the reflection will end up.
 +
 
 +
Well... that's it. We also used it indoors. Be extra careful about reflecting surfaces (mirrors, plastic, metal, ...) though!
 +
 
 +
How we dealt with the crowd while using the laser: tell them how freaking dangerous it is, suddenly nobody gets in the way. Basically nobody gets in the way anyway after realizing that you can see the laserbeam in air.
 +
 
 +
Good luck!

Laser Safety

I've just received a 15mW green laser from WickedLaser, and I'm terribly afraid of the safety guidelines to not harm myself and others, could you explain a bit more about it?

  • is it safe to use indoor?
  • laser point is really bright when nearer than 5 meters, is it dangerous?
  • which is the best laser to use? links to laser shop
  • Laser Tag from GRL is perfect with its target far above heads, how to deal with a crowd when using laser?

Well... I think we used a 15, 20 or 30mW laser - don't know exactly. We followed two security guidelines and so far nobody got hurt:

  1. Don't point at people. DON'T! NEVAR! EVAR!
  2. Don't point at stuff that might reflect the laser. You can't know where the reflection will end up.

Well... that's it. We also used it indoors. Be extra careful about reflecting surfaces (mirrors, plastic, metal, ...) though!

How we dealt with the crowd while using the laser: tell them how freaking dangerous it is, suddenly nobody gets in the way. Basically nobody gets in the way anyway after realizing that you can see the laserbeam in air.

Good luck!
