| 摘 要： | 报道了采用不等长电极结构的射频激励双通道波导CO2激光器,通过调节射频电源功率的方法可以调谐双通道输出激光的外差频率,其调谐率约为0.1 MHz/W。在未采取任何稳频措施时,其短期外差频率稳定性可达10-10。还在理论上分析了射频功率调谐外差频率的原理。

| Abstract: | Rf excited two-channels waveguide CO2 laser with the construction of unequally long electrode is present. The offset frequency of laser fr om the two channels can be changed by adjusting the RF input power, the slope of the tuning is about 0.1 MHz/W. The offset frequency stability of short term ca n be up to the order of 10-10 without any additional measure being taken to stabilize the frequency. In addition, a theoretical analysis is made for the o ffset frequency being tuned by RF input power. |
