FIELD: engineering of gas-based lasers, possible use for engineering gas lasers.
SUBSTANCE: nozzle block of mixture gas-dynamic laser includes a two-dimensional ultrasound nozzle, wing-shaped injector. Wing-shaped injector is provided with two channels. One of aforementioned channels serves for cooling the injector. Another one of aforementioned channels is utilized for delivering one of laser mixture components through injection apertures. Injector is shifted towards pre-sound area of nozzle. End edge of injector is positioned at a distance, exceeding height of critical cross-section of nozzle. Each injecting aperture is provided with a pipe. Injecting ends of pipes are positioned not higher along the ceiling, then is the critical cross-section of the nozzle. Pipes in cross-section of the nozzle are mounted evenly.
EFFECT: increased efficiency of mixture gas-dynamic laser.
