Krypton laser is an ion laser, a type of gas laser using krypton ions as a gain medium, pumped by electric discharge. Argon laser is very similar, using argon ions. From left to right: 1 mW Uniphase HeNe on alignment-rig, 2 Watt Lexel 88 Argon Ion laser, and power-supply. ... The gas laser is a kind of laser in which some sort of gas (such as helium or neon) is discharged to produce the laser light. ... General Name, Symbol, Number krypton, Kr, 36 Chemical series noble gases Group, Period, Block 18, 4, p Appearance colorless Atomic mass 83. ... // An ion is an atom, group of atoms, or subatomic particle with a net electric charge. ... A laser system generally consists of three important parts: An energy source (usually referred to as the pump or pump source); A gain medium or laser medium; A mirror, or system of mirrors, forming an optical resonator. ... Laser pumping is the act of energy transfer from an external source into the laser gain medium. ... a localised surplus of electrons migrates from the negative pole to the positive pole to overcome its unfavourable energetic condition. ... General Name, Symbol, Number argon, Ar, 18 Chemical series noble gases Group, Period, Block 18, 3, p Appearance colorless Atomic mass 39. ...

Krypton lasers are used for scientific research, or when krypton is mixed with argon, for creation of "white-light" lasers, useful for laser light shows. Krypton lasers are also used in medicine (eg. for coagulation of retina), for manufacture of security holograms, and numerous other purposes. Human eye cross-sectional view. ... This article is about the photographic technique. ...

Krypton lasers emit at several wavelengths through the visible spectrum: at 406.7 nm, 413.1 nm, 415,4 nm, 468.0 nm, 476.2 nm, 482.5 nm, 520.8 nm, 530.9 nm, 568.2 nm, 647.1 nm, 676.4 nm.

Argon lasers are used for retinal phototherapy (for diabetes), lithography, and pumping other lasers. Human eye cross-sectional view. ... Light therapy or phototherapy consists of exposure to specific ranges of light wavelengths (using lasers or LEDs), or very bright, full-spectrum light, for a prescribed amount of time. ... This article is about the disease that features high blood sugar. ... Negative litography stone and positive print of a map of Munich Lithography is a method for printing on a smooth surface. ... Laser pumping is the act of energy transfer from an external source into the laser gain medium. ...

Argon lasers emit at several wavelengths through the visible and ultraviolet spectrum: 351 nm, 454.6 nm, 457.9 nm, 465.8 nm, 476.5 nm, 488.0 nm, 496.5 nm, 501.7 nm, 514.5 nm, 528.7 nm.

Common argon and krypton lasers are capable of emitting continual wave output of several milliwatt for tens to hundreds of seconds. Their tubes are usually made of kovar, beryllium oxide ceramics, or copper. Kovar is a nickel-cobalt ferrous alloy. ... Beryllium oxide (BeO) is a white crystalline oxide. ... ‹ The template below has been proposed for deletion. ... General Name, Symbol, Number copper, Cu, 29 Chemical series transition metals Group, Period, Block 11, 4, d Appearance metallic brown Atomic mass 63. ...

In comparison with the helium-neon lasers requiring just a few milliamps, the current used for pumping the krypton laser ranges in several amperes, as the gas has to be ionized. The ion laser tube produces a lot of waste heat and requires active cooling. A helium-neon laser, usually called a HeNe laser, is a type of small gas laser. ...

A mix of argon and krypton can result in a laser with output wavelength appearing as white light.
