PURPOSE:To improve specific output by forming a discharge space to a combustion chamber having a nozzle for injecting combustion gas, and providing a diffuser disposed on the other end plate in a tank, and an optical resonator for forming an optical axis perpendicular between a combustion gas flow and the space. CONSTITUTION:Fuel and oxidizer separately injected from an injector 7 are ignited and burned by an ignitor 8 in a combustion chamber 3, combustion gas is injected from multihole nozzle 14 into a discharge space 18, adiabatically expanded to reduce its temperature and pressure, and fed into a diffuser 4 as an ultrasonic gas flow. Since the kinetic energy of the gas flow is converted to pressure energy and temperature, the pressure becomes higher than the atmospheric pressure in the diffuser 4 to be discharged into the atmosphere. Electromagnetic energy is stored in a cavity 19, the gas flowing in the space 18 is excited, a generated laser beam is amplified by an optical resonator made of mirrors 5a, 5b provided at optical ports 11a, 11b, and emitted externally. |
