Abstract:
1. CO 2 radio frequency (RF) gas-discharge laser apparatus, comprising: a laser housing formed from an elongated metal extrusion, the extrusion configured to permit passage of coolant fluid therethrough for cooling the housing; first and second elongated discharge-electrodes located in the laser housing, spaced apart and parallel to each other defining a discharge gap therebetween, the first electrode functioning as a live-electrode and the second electrode functioning as a ground electrode, the discharge-electrodes being configured to permit passage of coolant fluid therethrough for cooling the electrodes; first and second resonator mirrors defining a laser resonator extending through the discharge-gap between the discharge-electrodes; and a radio-frequency power-supply (RFPS) and an impedance-matching network located in the laser housing for supplying RF power to the electrodes for creating a RF discharge in the discharge gap for causing a laser beam to be generated and delivered from the laser resonator, the RFPS being assembled on an elongated metal mounting-plate configured to permit passage of coolant fluid therethrough for cooling the RFPS assembled thereon.
