摘要 | With consideration of the temporal characteristics of the electro-optically cavity-dumped seed laser and fast-axial-flow CW amplifier, a mathematical model describing the dynamic process of nanosecond-pulse CO2 laser amplification is established based on the six-temperature model. This theory perfectly studies the behavior of the CO2 amplifier gain characteristics and variation in the pulse waveform of a nanosecond input pulse. The dependence of the small-signal gain of the amplifier on the discharge current, gas pressure and ratio of CO2 and N-2 is studied on theory and experiment, and the evolution of the pulse shape in the gain-extracting stage is simulated. The calculated small-signal gain and output pulse waveforms are in good agreement with the experimental results. The theoretical model can be used to optimize and simulate the amplification performance of a nanosecond-pulse CO2 laser. |
