ABSTRACT
To realize a CO2 laser oscillator using a fast-axial-flow high-power microwave discharge excitation, we devised a method of making microwave discharge uniform by varying the oscillation direction of an electric field with time and verified the effectiveness of this method. When five orthogonal electric fields units were arranged in series for one laser tube, a maximum laser output power of 609 W and a laser efficiency of 17.0% were achieved for a microwave input power of 3590 W. In addition, using eight laser tubes, namely, 40 orthogonal electric fields units, we achieved a maximum laser output power of 3.6 kW and a laser efficiency of 13% for a microwave input power of 27 kW. Thus, a high-power microwave-discharge-excited CO2 laser has become feasible.
