 What is a laser pointer?

  laser pointer is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light.

 

Why is it  green laser ,not red ?

Just about everyone has a  red laser pointer ,But I am pretty sure you will abandon it when you see the green laser .The green laser pointer is significantly brighter (about 50 times )than a red laser pointer,Because of its unusual color ,it is much more noticeable,I mean the 532nm wavelength green laser is obviously superior to a 635nm wavelength red laser ,and unlike red laser,The green beam itself can be seen in the in mid-air in the dark conditions ,not just the beam dot.
