Laser Light Show

Laser Light Show term is using lasers and a projection system that is used in a laser projector. Creative Laser Media & Design is North America's largest manufacture of laser light show equipment.

Laser light shows were announced in the late 60's in the disco scene and Pink Floyd Band really pushed the era of laser shows and set a trend for lasers for entertainment throughout the world and now very popular today.

Lasers can be a gas filled ion laser. Ion lasers can use Argon gas, Krypton Gas, Co2,Copper Vapor and more.

Some lasers are not visible and some are. This all depends on the color wavelength that are eyes see.

Wavelengths that are visible have the following :

Violet Light Shades

The visible violet light has a color wavelength of about 400nm. Within the visible wavelength spectrum, violet and blue wavelengths are scattered more efficiently than other wavelengths. The sky looks blue, not violet, because our eyes are more sensitive to blue light and darker colors (the sun also emits more energy as blue light than as violet).

Indigo Light Shades

The visible indigo light has a wavelength of about 445 nm.

Blue Light Shades

The visible blue light has a wavelength of about 475 nm. Because the blue wavelengths are shorter in the visible spectrum, they are scattered more efficiently by the molecules in the atmosphere. This causes the sky to appear blue.
blue spectrum.

Green Light Shades

The visible green light has a wavelength of about 510 nm. Grass, for example, appears green because all of the colors in the visible part of the spectrum are absorbed into the leaves of the grass except green. Green is reflected, therefore grass appears green.
green spectrum.

Yellow Light Shades

The visible yellow light has a wavelength of about 570 nm. Low-pressure sodium lamps, like those used in some parking lots, emit a yellow (wavelength 589 nm) light.
yellow spectrum.

Orange Light Shades

The visible orange light has a wavelength of about 590 nm.

Red Light Shades

The visible red light has a wavelength of about 650 nm. At sunrise and sunset, red or orange colors are present because the wavelengths associated with these colors are less efficiently scattered by the atmosphere than the shorter wavelength colors (e.g., blue and purple). A large amount of blue and violet light has been removed as a result of scattering and the longwave colors, such as red and orange, are more readily seen.
