Diode-Pumped High-Energy Pulsed Nd: YAG Lasers

摘要

Laser diode-pumping of solid state laser materials, Nd:YAG in particular, is atpresent an area of intensive research and developmental efforts. These all-solid-state devices, as compared to lamp-pumped systems, hold numerous advantages, a sampling of which includes high electrical efficiency, long active lifetime, simplicity of use, low thermal loading, and reduction of size. Current commercial diode-pumped devices are generally limited in power (<1 W). However, with the advent of high-out, quasi-CW AlGaAs laser diode arrays, it has now become possible to develop diode-pumped lasers with pulsed energies in the joule range.
