Abstract

The invention belongs to the field of laser technology, and specifically relates to a semiconductor pumped gas laser system based on an electromagnetic drive mode, including a laser working medium generating device based on an electromagnetic drive mode, a plume area, and a semiconductor pump system; when the system is working, the laser The working medium generating device ionizes the working medium under the action of electric field and magnetic field to generate plasma, and the plasma is accelerated under the combined action of electromagnetic field to form a plume area, which can be used as the working medium of the laser gain medium in the semiconductor The laser output is realized under the pumping action of the pumping system; at the same time, due to the high-speed movement of the working medium in the plume area, the waste heat generated during the laser pumping process is efficiently discharged; it has all-electric operation, light weight and compactness, high specific power, and high efficiency The advantages of thermal control and single-aperture output promote the development of a new generation of laser light sources with high electro-optical efficiency, high beam quality and high average power.

Description

technical field

[0001] The invention belongs to the technical field of lasers, and in particular relates to a semiconductor pumped gas laser system based on an electromagnetic drive mode. Background technique

[0002] Since the advent of lasers in the 1960s, people have been devoting themselves to the development of laser systems with high average power, high conversion efficiency and high beam quality, which have important applications in fields such as industry and national defense. The essence of the laser system is to convert the pump energy (such as chemical energy, electrical energy, light energy, etc.) into a laser output with high coherence and low entropy. It leads to the deterioration and damage of laser system performance, and is more obvious in high-energy laser systems. The key to the development of high-energy laser systems lies in thermal management.

[0003] As the only light source that achieves megawatt-level output at present, the chemical laser is not on...
