| has gloss | eng: 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. When the number of particles in one excited state exceeds the number of particles in the ground state or a less-excited state, population inversion is achieved. In this condition, the mechanism of stimulated emission can take place and the medium can act as a laser or an optical amplifier. The pump power must be higher than the lasing threshold of the laser. |
| lexicalization | eng: laser pumping |
| instance of | (noun) an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light optical maser, laser |
