METHOD OF GENERATION OF HIGH-POWER RADIATION LASER IN FLOW CO LASER Russian patent published in 1994 - IPC

FIELD: laser equipment. SUBSTANCE: in flow CO₂ laser air stream after outlet device is divided into two streams. One of them is directed into heater for its balanced heating followed with addition of M₁ to it and expansion into gratings of nozzles up to M1 number. Produced imbalanced mixture goes into resonator where laser radiation is formed. In the other part of air stream only oscillatory degree of freedom is excited, then CO₂ is added and mixture is expanded in nozzle gear up to M₂<M₁ number. So obtained mixture interacts with radiation and amplifies it. Simultaneously gas stream in resonator ejects stream in amplifier and after it everything is directed into evacuation system. EFFECT: enhanced efficiency. 1 dwg
