Abstract
A new type of CO2-laser with high-power capability is described. It employs fast axial flow driven by a high-frequency radial impeller. Due to the coaxial design which integrates discharge tube, blower, and gas cooler into a single cylindrical housing, a very compact laser unit is realized. The discharge is rf excited (13.56 MHz). With a specific input power of 21 W/cm3 an output of 800 W is generated at an efficiency of 16%. The discharge can easily be operated in a pulsed mode with frequencies up to 10 kHz.
