This is a typical amateur-astronomer's green laser pointer, shown with a simulated beam. It emits an intense, narrow beam of light that is visible for ...
Does the color of a laser pointer affect its safety? Or only its power?
The eye is the most sensitive to the color green - so green lasers of less power appear brighter then more powerful lasers with other colors.
