摘要：

A high power and high focusing CW CO2 laser with a novel unstable resonator is developed. This resonator contains a stepwise variable reflecting output coupler named "phase-unifying output coupler" and a total reflector. The laser is excited by the capacitive-barriered ac discharge called "silent discharge." A linearly polarized laser beam with the diffraction limited divergence angle of 0.55 mrad is obtained. Very stable CW laser operation at an output power of 5 kW is achieved with the threshold discharge power of 10 kW and the slope efficiency of 18%.
