Tunable RF-excited Z –fold waveguide CO2 laser with common electrodes

Abstract EN

The design and performance of radio frequency (RF) excited partial Z-fold waveguide CO2 laser with two channels are exposed.

The electrodes for the two channels are common and excited by a same RF source .According to our analysis, this kind of structure can greatly improve the laser offset frequency stability.

In the experiments, we studied the offset signal of laser form with two channels and the deviation of offset frequency in long term.
