Laser emission under resonant pump in the emitting level of highly doped Nd materials

Abstract

Heating effects in the laser active media Under pump constitute a major limitation in the construction of highly efficient or high-power solid state lasers. These effects could induce the optical distortion of the resonator or even the physical destruction of the active component. In case of neodymium-doped crystals two major sources exists: the quantum defect between the Pump and laser radiation and the non-radative processes (multiphonon relaxation, down conversion cross-relaxation on intermediate levels, upconversion from the emitting level4F3/2).
