Abstract

This paper is the first to report on the Optogalvanic Effect (OGE) of CO, waveguide laser with Compound Cavity. The study shows that as compared with common CO, laser, the OGE of CO, Waveguide laser is markedly more than that of common CO, laser. The OGE in a CO, Waveguide laser is caused by Changes in gas temperature (and hence resistivity) arising from variations in the collisional energy exchange rate between the two energy levels of the lasing transition and background gas. Therefore, the OGE is closely related with the Operated Conditions of laser, such as gas pressure, discharge current, gas mixture, modulated frequence of cut light, etc.
