Laser Pointer

laser pointer?

Should I get the 15MW 35 MW or 55mW laser pointer as a first for me? lasers have previously addressed and I do not think you can Add not melt in the plastic lid. I also wanted to know just look at the point you said hurt your eyes or just when you point to someone. What DIF. between green and red laser? Is their difference, but other colors? laser as orange $ 200 dollars more. What if the surface is not reflected?

Google "ANSI laser hazard class" for an explanation of the hazard classes in terms of power levels. A CW laser of 55 MW, for example, is a laser class III, which means it is powerful enough to do damage in the retina by the time it takes to blink. (Not a technical term for this, "does not like something I remember, the point is that if they gleam in the eye or eyes of others, could cause much damage.) I know that you may annoy, and I do not intend to be offensive but although it is possible that lasers are treated before, it seems you know much about them. A laser of 55 MW is not a toy, and if you buy something like it is a good idea to read about security issues. A green laser is commonly called a frequency doubled Nd: YAG laser. What it means is the laser wavelength near infrared primary and managed by a nonlinear crystal for frequency doubling (halving the wavelength) give something green. Green canonical Nd: YAG wavelength of 532 nm, but there are variations in which, as the new lasers do not use the state strong Nd: YAG oscillators primary, but other variants where Nd atoms are incorporated into a crystal YAG different. Orange A laser is a laser dual-frequency whose main oscillator is running at just over wavelength (ie far-infrared) Nd: YAG laser. red laser, in general, are laser diodes which are not dual-frequency. The main result of the laser is in the red. Therefore, in general, red pointers are cheapest green or other colors, there are fewer optical within them.
