Abstract : This patent discloses an improved gaseous laser device which comprises a generally tubular laser discharge tube having a laser window at each end thereof, each window disposed at an angle to the lasing axis of the device corresponding substantially to the Brewster's angle characteristic of the material comprising the windows, and including means directing substantially uniform flow of gaseous laser medium into and out of the discharge tube substantially at said angle and means providing a choked gaseous exhaust exit for canceling cavity disturbances within the device. Laser optics defining an optical resonant cavity of the laser device may be disposed external of the discharge tube and windows.
