Abstract

The invention discloses a preparation method and apparatus of a composite laser gain medium, wherein the preparation method includes the steps of designing, to be specific, designing a plurality of function regions which the laser gain medium have, according to functions of the composite laser gain medium to be prepared, and determining parameters of each layer of material in the composite laser gain medium; laying materials, to be specific, laying corresponding prefabricated materials according to the parameters of each layer of material layer by layer to form the function regions in preset shape, so that a blank having the function regions is attained; sintering, to be specific, sintering the blank to obtain the composite laser gain medium. The preparation method of the composite laser gain medium has low cost and high yield; the interior structure of the laser gain medium can be precisely controlled; a broad design space is provided for the laser gain medium; energy storage capacitycan be greatly improved, and wavefront distortion can be actively compensated.

Description

technical field [0001] The invention relates to the field of laser application technology, in particular to a preparation method and device of a composite structure laser gain medium. Background technique [0002] All-solid-state high-power high-beam-quality lasers have broad application prospects in scientific research, medical treatment, communications and other fields, and thus become one of the current research hotspots in the field of laser technology. When the bulk solid-state laser as the laser gain medium performs laser amplification, the phenomenon of photoelastic effect, thermo-optic effect and thermal deformation of the laser will occur due to waste heat, which will degrade the quality of the laser beam and limit the increase of the output power. In order to keep the laser running stably and with high performance, the waste heat must be taken away in time. The corresponding improvements and innovations are mainly in the change of the gain medium structure and the...
