报道了光栅选支射频激励共电极双通道波导 CO2 激光器。双通道输出激光方向相反 ,在复杂环境下 ,未采取任何稳频措施时 ,其短期外差频率稳定性可达 1× 10 -9,在 1min内外差频率漂移小于 2 MHz Reported a grating-supported RF excitation common-mode dual-channel waveguide CO2 laser. In the complex environment, the short-term heterodyne frequency stability is up to 1 × 10 -9 when the frequency of the laser light is opposite to that of the dual-channel output laser. In one minute, the heterodyne frequency drift is less than 2 MHz
