Problems solved by technology

But this XeF 2 The gas supply device has the following deficiencies: first, for XeF 2 The control and adjustment of gas concentration is inconvenient and the adjustment time is long, resulting in a large amount of XeF 2 Gas waste; second, the use of premix tanks, the device has a complex structure and a large volume; third, the preparation time is long; fourth, the output gas flow rate is small, only a dozen liters per second
These deficiencies lead to XeF 2 The gas supply device cannot be used to develop a higher repetition rate open XeF(C-A) blue-green laser

Abstract

The invention discloses an automatic mass-flow XeF2 gas supply device for a multi-frequency blue-green laser. Based on a shunt mix principle, argon-nitrogen mixed gas is divided into two paths, small gas flow brings out a certain quantity of XeF2 gas from branch gas paths to be mixed with big gas flow in a main gas path, then the mixed gas is delivered to a laser gas chamber, and the concentration of the XeF2 gas is automatically regulated by controlling the gas flow of the branch gas paths. The flow of the mixed gas in the main gas path and the branch gas paths is regulated by a gas mass flow controller. The automatic mass-flow XeF2 gas supply device achieves automatic control, is easy and convenient to use, reduces waste, improves the cost-effectiveness of an experiment, effectively shortens preheating time, shortens early-stage gas supply preparation time, improves experiment efficiency, and is successfully applied to the open type multi-frequency XeF (C-A) blue-green laser.

Description

technical field [0001] The present invention relates to a XeF (C-A) blue-green laser gas medium supply device, in particular to an open repetition frequency XeF (C-A) blue-green laser XeF 2 Gas supply device. 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 ultraviolet band (130-180nm) generated by surface discharge, and after photodissociation to for...
