ABSTRACT:
A method of lasing gas, a fast axial flow gas laser and an excitation tube for a fast axial flow gas laser are disclosed. Increased thermal energy per mass flow unit of the gas flowing through the excitation tube of the laser can be applied to the gas by controlling at least along a part of the tube the extent of a central area of higher speed gas flow which is surrounded by a circumferential low speed, speed dependent boundary layer by steadily varying the cross-section area of the excitation tube at least along the part thereof to compensate for the circumferential low speed boundary layer.
