List of laser types

Columns: Laser gain medium and type | Operation wavelength ( s ) | Pump source | Applications and notes
Chromium ZnSe ( Cr : ZnSe ) laser | 2.2 - 2.8 μm | Other laser ( Tm fiber ) | MWIR laser radar , countermeasure against heat-seeking missiles etc | Cerium -doped lithium strontium ( or calcium ) aluminum fluoride ( Ce : LiSAF , Ce : LiCAF ) | ~280 to 316 nm | Frequency quadrupled Nd : YAG laser pumped , excimer laser pumped , copper vapor laser pumped | Remote atmospheric sensing , LIDAR , optics research | Promethium 147 doped phosphate glass ( Pm : Glass ) solid-state laser | 933 nm , 1098 nm | ? ? | Laser material is radioactive . Once demonstrated in use at LLNL in 1987 , room temperature 4 level lasing in Pm doped into a lead- indium -phosphate glass étalon | Chromium -doped chrysoberyl ( alexandrite ) laser | Typically tuned in the range of 700 to 820 nm | Flashlamp , laser diode , mercury arc ( for CW mode operation ) | Dermatological uses , LIDAR , laser machining | Erbium -doped and erbium - ytterbium codoped glass lasers | 1.53-1.56 μm | Laser diode | These are made in rod , plate/chip , and optical fiber form . Erbium doped fibers are commonly used as optical amplifiers for telecommunications | Trivalent uranium -doped calcium fluoride ( U : CaF 2 ) solid-state laser | 2.5 μm | Flashlamp | First 4-level solid state laser ( November 1960 ) developed by Peter Sorokin and Mirek Stevenson at IBM research labs , second laser invented overall ( after Maiman 's ruby laser ) , liquid helium cooled , unused today .
