Lasing threshold — The lasing threshold is the lowest excitation level at which a laser s output is dominated by stimulated emission rather than by spontaneous emission. Below the threshold, the laser s output power rises slowly with increasing excitation. Above… … Wikipedia
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… … Wikipedia
