Abstract:
A microwave excited gas laser oscillator comprising:a discharge tube containing a laser gas;a plurality of microwave generating units, each of said plurality of microwave generating units comprising:a microwave generator operable to generate microwaves,a power source operable to supply power to said microwave generator, anda waveguide coupling said microwave generator to a discharge area of said discharge tube and operable to inject the microwaves generated by said microwave generator into said discharge area to thereby discharge and excite the laser gas; anda controller operable to drive and control each of said plurality of microwave generating units, wherein said waveguides of said plurality of microwave generating units are connected along said discharge tube at discharge areas and said controller is operable to drive microwave generating units having waveguides that are connected along said discharge tube at adjacent discharge areas at a specific phase difference such that said microwave generating units having said waveguides that are connected along said discharge tube at adjacent discharge areas are not driven during a same time period.
