Abstract

The invention relates to the technical field of all solid-state lasers, and specifically discloses a novel laser amplifier. The novel laser amplifier of the present invention includes: an optical prism 2 arranged along the optical path, a laser working substance 1 and an optical prism 3; wherein, the laser working substance 1 is a tube-shaped rod-shaped crystal, and the two ends of the tube-shaped rod-shaped crystal are directed toward The chamfer is processed inside or outside, and the section of the tubular rod crystal is trapezoidal; all surfaces of the laser working substance 1 are precisely polished; the optical prism 2 and the optical prism 3 are the same. Compared with the traditional rod-shaped working substance, the present invention effectively reduces the internal thermally induced refractive index gradient, so the thermally induced refractive index gradient is greatly reduced, and the difference in optical length experienced by the beam passing through different positions of the crystal is reduced, which can effectively weaken the beam The generated wavefront distortion; the production is simple and the cost is low, and it is easy to meet the precision requirements of the processing technology.

Description

technical field [0001] The invention relates to the technical field of all-solid-state lasers, in particular to a novel laser amplifier. Background technique [0002] High average power and high beam quality lasers have a wide range of applications in industry, medical, national defense, scientific research and other fields. However, in all solid-state laser systems, a part of the pump light absorbed by the laser medium is converted into heat energy and deposited inside the medium; at the same time, the laser medium is cooled by the outside, so that a non-uniform temperature field distribution is formed inside the laser medium. The inhomogeneous distribution of thermal strain and thermal stress is formed in the medium, and the change of the refractive index of the medium caused by thermal stress will cause the thermally induced birefringence effect. [0003] In many laser systems, the polarization state of the laser light is required to be linearly polarized light. Therefo...
