KTP

Potassium Titanyl Phosphate, A crystal used to change the wavelength of an Nd:YAG laser from 1060 nm (infrared) to 532 nm (green).

Krypton Fluoride Laser

The krypton fluoride laser is a member of the excimer laser family and produces high-energy laser pulses at 248 nm. Pulse widths in commercial systems range from 20 to 30 nsec, with pulse repetition rates of up to 2000 Hz. Pulse energy can be over 1 J/pulse.

Krypton-Ion Laser

The krypton-ion laser is a member of the gas-ion laser family. These lasers produce output primarily in the yellow, red, and near-infrared regions of the spectrum. They have been used extensively in scientific and entertainment applications.

Krypton-ion lasers are divided into two broad classifications: air-cooled systems and water-cooled systems. The output of air-cooled systems is limited to a few hundred milliwatts, multiline. Water-cooled systems are available with powers as high as 6 W multiline and in the visible and more than 5 W single line at 657.1 nm (red).

The main laser wavelengths for krypton-ion lasers are: 647.1 nm (red), 568.2 (yellow) and 752.5 (near infrared). There are additional lines in the visible and ultraviolet, but they are used infrequently.

Krypton/Argon Laser

The argon/krypton laser (also known as a mixed-gas laser) is a member of the gas-ion laser family. They are unique in their ability to simultaneously produce significant output in blue (488.0 nm), green (514.5 nm), yellow (568.2 nm), and red (647.1 nm) wavelengths. If so configured, the output will appear to be white light. Krypton/argon lasers are available in air-cooled or water-cooled formats. The output power of the air-cooled lasers is limited to multiline output power of significantly less than 1 W. Water-cooled lasers are available with output as high as 10 W.
