How does the color of a laser affect the light wave projected by the laser?

Answer 1

Our eyes/brain perceive colors based on the wavelength of the light. So in other words, the wavelength of the light projected by a laser is based on the color. (Really, the terms color and wavelength are the same thing, except that color implies more about how we perceive it than the physics of the light wave itself).

Longer wavelengths of light are red in color (eventually becoming infrared, which we can't see). The shortest wavelengths we can see are violet (which becomes invisible ultraviolet as it gets shorter).

Answer 2

Laser light is directional, coherently organized, and monochromatic. The color emitted is more a byproduct of the energy released, than the other way around. The wavelength of light you see results from the energy difference between the excited atomic state and the ground state This relationship partially determins the laser's intensity. Lasers that produce a beam of energy in the infrared and microwave range are the most dangerous and some emitt energy that is not visable as light. Some in this range can cut through concrete or even dense metals.

Answer 3

Each color has a different wavelength from the other colors. The shorter the wavelength the higher the energy of the light. Red is the longest wavelength of light that the human eye is able to see, it is also the lowest energy. Think about it, most lasers you see are red. Green lasers have a higher energy since green light has a shorter wavelength. Green lasers are great for pointing out stars and constellations at night.

Answer 4

The color refers to what part of the visible spectrum is being emitted.
