Laser pumping 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 in the ground state or a less excited state population inversion is achieved
