2 kW transverse-flow closed-cycle CO2 laser
The combination of a closed-cycle,transverse-flow 2KW CW CO2 laser is described with emphasis on the arcless elecrode construction and glow discharge characteristics.By means of a multi-pin trigger,the glow discharge stability is appreciably increased at more intense input current. The direct current output characteristics of the main supply and the selection of the ballast resistor greatly affect the glow discharge stability and the output power. When the gas flow velocity in the discharge region is 40 m/s,the gas mixture pressure is 46 mmHg,the length of active region is 86 cm,a CW multimode output power of more than 2 KW and an electro-optic efficiency of about 15% are achieved.
