Abstract
The present invention provides a novel and improved technique for achieving a combined RF-DC gas discharge in the optical cavity of the gas laser. The combination of the fast pre-ionization with the transverse RF discharge and the high power excitation with the highly-efficient longitudinal DC discharge allows for a high-speed laser gain modulation of the active medium of the high-power gas laser. At the same time, the all-metal electrode system allows for a very compact, reliable and low cost design of the gas laser.
