摘要	In order to obtain a high-quality single-longitudinal-mode output from a TEA CO2laser, a study on a TEA CO2laser with seed injection locking is carried out. A virtual confocal resonator with transmission coupling is proposed. The evolution of the cavity mode is simulated by Prony's method of the Glad software. The near-field and far-field intensity distributions are recorded experimentally. The results demonstrate that the simulation results are in good agreement with the experimental results, which verifies the rationality of the cavity scheme. On the basis of this resonator, the experiment of seed injection locking is carried out. The experimental results show that there is a beat signal with a frequency of 195 MHz when the oscillation of unstable resonator is free. When the seed injection is successfully locked, the output laser beat disappears, the waveform becomes smooth, the peak power is reduced by 48.6%, and the pulse generation time is shortened by 20 ns. The experimental results agree well with the existing results, which verifies that the TEA CO2laser with such a transmissive unstable resonator has the ability to output a high-quality single longitudinal mode. 2018, Science Press.
