A CO2 laser with a resonator frame made of low expansion ceramics has been developed to provide superior passive stability properties. High stiffness, low specific weight, and very good electric insulation properties recommend ceramic as an attractive material for many laser applications. The long-term power stability of a first prototype was better than ±0.44% measured over 15 min, the short-term stability was better than ±0.24%. Both values were achieved without any active stabilization technique, without damping of external vibrations, and with a non-temperature-controlled coolant. With a new switch mode power supply without ballast resistor a wall-plug efficiency of about 14% has been achieved under quasi-sealed-off conditions. The specific laser output power was about 20 W/m at a gas pressure of 18.5 mbar and a gas mixture He:N2:CO 2=75:15:10+5.5% Xe. © 1995 American Institute of Physics.
