Default Some questions about green lasers

Hi everybody,

1 From how much mW can a green laserpointer begin to sting on your skin?

After 1 minute for example?

2 How much mW will a laser be, when it stings and hurts immediately on my skin?

3 Can a simple 5 mW green laser sting on the skin?

Thanks to everybody who will help me with this questions.

Remco

Depends on power density (W*cm^2) not power.

Default Re: Some questions about green lasers

Is it not dangerous, when i let my 300 mW green 532 nm laserpointer sometimes sting on my arm/skin?

Is it safe, when you off course not let your skin burn?

I do this for a month sice i have a 300 mW green laser, sometimes point it on my arm, and feel it sting.

I have also a 300 405 nm violet laser, but do NOT try to point that on my skin, because i not know if that is safe or not, to do with a violet laser.

Thanks,

Remco

Sounds like a personal problem. Self mutilation is a serious issue. You should seek psychological help, I wish you the best of luck.
