Tunable RF-Excited Z –Fold Waveguide CO2 Laser With Common Electrodes

Abstract

The design and performance of radio frequency (RF) excited partial Z-foldwaveguide CO2 laser with two channels are exposed. The electrodes for the two channelsare common and excited by a same RF source .According to our analysis, this kind ofstructure can greatly improve the laser offset frequency stability. In the experiments, westudied the offset signal of laser form with two channels and the deviation of offsetfrequency in long term.
