Abstract: A brief introduction is given to the working principle and the outstanding characteristics of solid propellant combustion driven continuous-wave co2 laser system. Some concise descriptions about the major parts such as solid propellant gas generator, supersonic mixing chamber, nozzle band and resonator of the 10kW experimental system are psented also. Over one hundred parameter-measuring or target-shooting tests have been done successfully by the use of the test system and some necessary discussions and analysis are conducted to the experimental results.
