Abstract:
1. A CO 2 gas laser device for amplifying CO 2 laser light which repeatedly oscillates in a short pulse having a pulse width of 100 ns or less, wherein a CO 2 laser gas which is excited by continuous discharge is cooled by circulating the gas by forced convection, the CO 2 gas laser device comprising: a plurality of amplifiers, wherein an angle θ defined by an optical axis of the amplified CO wherein S the plurality of amplifiers each including discharge electrodes which are opposite to each other, between which the CO the plurality of amplifiers including a first amplifier and a second amplifier, the first amplifier amplifies the CO wherein the laser beam passing through the second amplifier first makes contact with one discharge electrode, and then makes contact with another discharge electrode opposite to the one discharge electrode, and wherein the CO
