Anode gas incoming nozzle for high-power gas laser device

Abstract

The invention discloses an anode gas incoming nozzle for a high-power gas laser device. The anode gas incoming nozzle comprises a crossed discharging tube, an anode needle seat, an anode needle and a ceramic porous nozzle, the anode needle seat is fixed at a gas inlet of the crossed discharging tube, the ceramic porous nozzle is fixed on the anode needle seat and faces a crossed cavity of the crossed discharging tube, and the anode needle is fixed on the anode needle seat and corresponds to a gas turbulence hole formed in the ceramic porous nozzle. By the anode gas incoming nozzle, turbulence of gas can be realized more easily, turbulence effect at the anode needle can be realized easily, gas flow can be increased, gas flowing speed of a discharging tube discharging area namely a straight tube portion is increased, gas temperature is lowered effectively, and discharging stability is improved. Gas incoming from multiple holes generate multiple branches of turbulent cyclone, each section of the discharging tube can be charged fully better, and the discharging tube is more uniform in gas density distribution; due to good turbulence, discharging stability is improved, and high power can be realized more easily.

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...
