The wavelength of red laser light is between 620 and 750 nanometers (billionths of a meter). Anything emitting or reflecting light in that wavelength is perceived by us (human beings) as red.
If the light were in the range of 495 to 570 nanometers, it would appear green, and would seem even brighter at the same energy level. For this reason green lasers make great pointers for stellar objects in dark skies.

∙ 14y agoNot all lasers are red. You can buy green laser pointers, and laboratory lasers come in a wide variety of colors, including tunable dye lasers in which it's actually possible to adjust the color of the beam. A laser is the color it is (whatever that color might be) because an electronic transition in the material that makes up the laser has exactly the same energy as a photon of that particular frequency/wavelength.

Due to this Laser beam is very sharp and bright Unlike torches and lamps whose waves spread.

From NOAA Lightning can appear to be many different colors depending on what the light travels through to get to your eyes. In snowstorms, where is somewhat rare, pink and green are often described as colors of lightning. Haze, dust, moisture, raindrops and any other particles in the atmosphere will affect the color by absorbing or diffracting a portion of the white light of lightning.

What causes red lightning?
Heat lightning is actually ordinary light that is simply too far away for. Lightning is causes as water droplets and ice crystals in a thunderstorm collide and build up electrical charges. These charges are eventually released in massive discharges called lightning.
