Study of Offset Frequency Modulation of RF Excited Waveguide CO2 Laser with Two Unequally Long Electrode Channels
【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 .1MHz/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 CO 2 laser with the construction of unequally long electrode is present The offset frequency of laser from 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 can 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 offset frequency being tuned by RF input power
