| Abstract: | An introduction is given to the principle, method and experiment system of measurement of small-signal gain on solid propellant combustion driven CO 2 gasdynamic laser. Measure optical path design of small-signal gain, operating principle of thermistor infrared detector, design of filter and amplifier circuit of gain output signal and hardware configuration as well as rules and methods of software development of data acquisition system are mainly presented. The typical experimental results are also given, which show that the amplification method can measure the small-signal gain accurately. |
