Abstract

For a laser system with fast longitudinal gas flow, at least one impeller of the type of runners for tangential blowers with adjacent ring channel is used for the circulation of laser gas. At least two longitudinal pipes merge tangentially into the ring channel where at least one longitudinal pipe is designed as a laser resonator. The ring channel and the longitudinal pipes form a closed loop for the laser gas.
