Abstract

The invention discloses a closed circulating repetition-frequency optical pumping xenon fluoride laser system which comprises a discharge pumping source, a resonant reflection mirror, an output cavity mirror, a laser cavity and a gas supply device, wherein the laser cavity is a square cavity, and the length, width and height directions of the laser cavity correspond to an optical axis direction, a dissociative direction and a gas flow direction respectively; the gas supply device is at least one closed circulating pipeline connected to two end surfaces in the height direction of the laser cavity; an axial-flow fan is arranged in the middle of the closed circulating pipeline and can be used for enabling XeF2 gas prefilled in the closed circulating pipeline to circularly flow in the pipeline. All pipelines of a laser are connected to form the closed circulating pipeline, and the axial-flow fan is utilized for driving laser mixed gas to circularly flow in the pipeline, so that high-power and multi-pulse repetition-frequency running of the XeF(C-A) laser is realized, the gas utilization rate is increased, gas waste is reduced, and caused environmental pollution is alleviated.

Description

technical field [0001] The invention relates to a gas closed-cycle repetitive frequency optically pumped xenon fluoride laser system, which belongs to an excimer gas laser, in particular to an optically pumped XeF (C-A) laser capable of repeated frequency operation. Background technique [0002] The output wavelength of the XeF(C-A) blue-green laser is 460nm~520nm, which is in the underwater and atmospheric transmission window. The single pulse energy reaches the ten-joule level, which is consistent with the requirements of the laser source for underwater laser communication, and also has a gain bandwidth. The advantages of very wide and tunable output wavelength, so the XeF(C-A) blue-green laser with high power and high repetition rate has a good application prospect in the field of laser underwater communication and underwater detection. From the process of XeF(C-A) blue-green laser output, XeF 2 Vapor molecules absorb photons in the vacuum ultraviolet band (130-180nm) ge...
