Abstract
A gas laser is designed with the following features: The laser is a slab laser, in which a plasma space (5) of a limited height is formed for the laser-active plasma between mutually opposing surfaces (11, 21) of two wall parts (10, 20); the wall parts (10, 20) are components of a coupling chamber with at least one coupling wall (30), which is connected to at least one distribution chamber (40,), whereby by injecting the high-frequency energy through the coupling wall (30), the gas plasma is activated in the desired manner over its entire length. The high-frequency energy for exciting the plasma lies in the gigahertz range, for which a magnetron is used, for example.
