In the case of umgebunsdruck operated, pulsed gas laser, gas laser, server stronger or corrugated layers narrow converter

摘要

the invention concerns a pulsed gas lasers operated at atmospheric pressure, or filled with gas, gaslaserverstu00e4rker wellenlu00e4ngenkonverter (laser)in a lasergasversorgung is connected and with a tubular, open in the vicinity of ausmu00fcndenden window for a laser beam is provided and carried.the invention has the task of $a, a gattungsgemu00e4u00dfen laser by simpleconstructive action on the equipment and betriebsmu00e4u00dfigen effort for the separation of lasergas and umgebungsgas window reduction.$a to the solution of this problem are the following features: (a) $a rohrfu00f6rmige window (5) has a volume that is a multiple of the change in the volume of the pulsbetrieb lasergases laser (1),3); $a (b) rohrfu00f6rmige window (5) in relation to its longitudinal axis (5a) is perpendicular or approximately perpendicular to the laser (1),3) appropriate and has its mouth (5c) in the same direction as the auftriebskraft of umgebungsgases in the mischzone (5b) of the window (5), the laser (1), pulsbetrieb3) training; $a (c) from the lasergasversorgung (2c) of the laser (1, 3) intake and the rohrfu00f6rmige window (5) abstru00f6mende lasergasmenge (2d) is so tightthat the concentration of the laser (1, 3) is below a predetermined threshold eindiffundierenden umgebungsgases.
