Optical Pumping – pump light, laser crystal, optically pumped …
网页The most common optically pumped lasers are doped-insulator solid-state lasers. As the host medium (a laser crystal, glass or piece of ceramic) is electrically insulating, optical pumping is the only way to supply the laser-active ions (e.g. rare earth ions) with energy. See Figure 1 as an example.
Laser pumping - Wikipedia
网页Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms.
Optical pumping - Wikipedia
网页Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion .

Pump Light - an overview | ScienceDirect Topics
网页A He-Ne laser (the energy range below 1.96 eV) or Ar+ ion laser (the energy range below 4.5 eV) is used as typical pump sources. The intensity of the laser light can be adjusted by a variable, neutral density filter. The light reflected from the sample is detected by a photodiode or a photomultiplier.
