Abstract

The invention relates to a laser amplifier comprising two pumping light sources, two pumping light coupling lens groups, a seed light source, a half wave plate, a polarizer, a polarization controller,a coupling lens, two deflecting mirrors, a laser crystal and a total reflector. The pumping light generated by one pumping light source is output to one pumping light coupling lens group through a fiber. The pumping light generated by the other pumping light source is output to the other pump light coupling lens group through another fiber. The two deflecting mirrors include a first deflecting mirror and a second deflecting mirror. The laser crystal is located between the first deflecting mirror and the second deflecting mirror to form a crystal gain region. The two pumping light coupling lenses are located at the other sides of the first deflecting mirror and the second deflecting mirror respectively. The seed light source, the half wave plate, the polarizer, the polarization controller,and the coupling lens are successively disposed. The laser amplifier can achieve amplification two times, and the amplified laser and seed light are isolated and output to enhance the applicability of the laser amplifier.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser amplifier. Background technique [0002] A laser amplifier refers to a device that uses stimulated radiation of light to amplify the energy (power) of light. By using a laser amplifier, the quality of the laser (including pulse width, line width, polarization characteristics, etc.) can be maintained while obtaining high laser energy or power. It is often used in controllable nuclear fusion, nuclear explosion simulation, ultra-far laser ranging, etc. High power laser systems in major technologies. However, the current laser amplifiers only perform one amplification, and the degree of laser energy amplification is limited, so they are not suitable for occasions with higher requirements. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies in the prior art and provide a laser amplifier. [0004] In order to achieve the pu...
