Abstract

The invention relates to a laser, in particular to a double-output end face pumping all-solid-state laser, comprising two pumping sources, a linear type resonant cavity, two dichroscopes and two gain media, wherein the first and second dichroscopes are respectively arranged on the output pumping optical path of the first and second pumping source and form a certain included angle with the output pumping optical path, to ensure that the refraction optical path of the dichroscopes to the pumping light coincide with the resonant optical path in the resonant cavity; and the first and second gain media are arranged on the linear type resonant optical path between the first and second dichroscopes. The invention aims at designing a double-output end face pumping all-solid-state laser which can simultaneously output two beams of laser beams with equal power; and compared with the prior art, the invention has the advantages of coincident physical parameters output by laser beams, great outputpower, strong applicability, high quality of light beams and the like.

Description

technical field [0001] The invention relates to a laser, in particular to a double-output end-face pumped all-solid-state laser. Background technique [0002] Diode-pumped all-solid-state lasers refer to lasers that use laser diodes instead of flash lamps to pump the gain medium of solid-state lasers. High reliability, solid structure, good beam quality and so on. [0003] The end-pumping method is to pump along the end face of the laser crystal. It is a common pumping method for laser diode pumped solid-state lasers. The laser gain medium is a solid medium that can be doped with high-concentration ions, so that the laser medium It is easy to form high power density laser photons, has high light-to-light conversion efficiency, and low laser output threshold. In the end-pumped all-solid-state laser, the laser beam output by the diode laser passes through the coupling fiber and the optical focusing system, enters the laser medium along the light-passing direction of the lase...
