Abstract
A diode laser pumped solid-state laser amplifier capable of homogenizing the distribution of heat dissipation levels on a section of a solid-state laser rod and not causing a bifocal phenomenon, and a diode laser pumped solid-state laser using the diode laser pumped solid-state laser amplifier. A diode laser pumped solid-state laser amplifier includes a solid-state laser rod having an optical axis along which a laser beam propagates and includes an active medium therein and a plurality of pumping sources having optical axes that run on a plane orthogonal to the axial core of the solid-state laser rod and are separated by a given distance from the axial core of the solid-state laser rod. When pumping light rays are projected on a plane orthogonal to the axial core of the solid-state laser rod, the plurality of pumping sources are located at equiangular intervals with respect to the axial core of the solid-state laser rod.
