An anode inlet nozzle for high power gas laser

Abstract

The invention discloses an anode inlet nozzle for a high-power gas laser, which includes a cross-shaped discharge tube, and also includes an anode needle seat, an anode needle and a ceramic porous nozzle, and the anode needle seat is fixed on the gas inlet of the cross-shaped discharge tube , the ceramic porous nozzle is fixed on the anode needle seat and faces the cross-shaped cavity of the cross-shaped discharge tube, and the anode needle is fixed on the anode needle seat and corresponds to the gas turbulence provided on the ceramic porous nozzle hole. The present invention is easier to realize the turbulent flow of gas, and it is easy to realize the turbulent flow effect at the anode needle, and at the same time, it can increase the gas flow rate, increase the gas flow rate in the discharge area of ​​the discharge tube, that is, the straight tube part, effectively reduce the gas temperature, and increase the discharge stability . Since the porous air intake produces multiple turbulent cyclones, it can better fill the various sections of the discharge tube, and the gas density distribution of the discharge tube is more uniform. With good turbulence, the discharge stability is increased, and it is easier to achieve high power.

Description

technical field [0001] The invention relates to an axial fast-flow gas laser, in particular to an anode inlet nozzle for a high-power gas laser. Background technique [0002] The anode inlet nozzle is an important part of the high-power gas laser. It is installed at the anode of the discharge tube 1, and is provided with an anode needle 2 and a gas turbulence hole 3. During operation, the gas is driven by a high-speed circulating fan to quickly pass through the discharge tube 1. The electrodes at both ends of the tube 1 generate an applied high-voltage electric field, and the working gas glow discharges in the cavity to generate a gain medium. In the resonant cavity composed of multiple sets of discharge tubes 1 and mirrors of the high-power gas laser, part of the energy generates laser output. The other part generates heat release. The flow rate of the working gas in the discharge tube 1, the uniformity of the gain material and the uniformity of the turbulence of the gas d...
