Abstract
The invention relates to a gas laser having a discharge tube, through which the gas flows in an aixal direction and to which high-frequency electrodes are fitted externally, and having a high-frequency generator. In order to obtain a simpler construction and the smallest possible high-frequency losses, it is provided that the power output stage (12) of the high-frequency generator is disposed in the housing (1) of the laser resonator (2, 7, 8) and is directly connected to the electrodes (9, 10) via impedance adaptation elements (11).
