This paper presents a scheme for electro-optic frequency shifting. In this scheme linearly polarized light of output from CO2 laser passes through a electro-optic modula-tor and retroaction-cycle laser amplifer, under the condition of no increased harmonic components exist, the convertion efficiency of the shifting can be raised greatly. This work suggests that electro-optic frequency shifting possesses potentiality of wide appli-cation. In the experiments on checking the effect of the frequency shifting, the...

This paper presents a scheme for electro-optic frequency shifting. In this scheme linearly polarized light of output from CO2 laser passes through a electro-optic modula-tor and retroaction-cycle laser amplifer, under the condition of no increased harmonic components exist, the convertion efficiency of the shifting can be raised greatly. This work suggests that electro-optic frequency shifting possesses potentiality of wide appli-cation. In the experiments on checking the effect of the frequency shifting, the experi-mental device is simplifed by auto-collmating round-trip of the light beam and space delaying the modulated signal. The frequency components of the frequency shifted light is analysed by using simple method of frequency beating.

It is believed that interference effect of Ge-window is an important factor affecting CO2 laser output staibilty. The two parallel surfaces of a Ge-window constitute a Fabry-Parot interferometer, so for an incident laser beam, the transmissivity depends sensitively on thickness as a result of interference. And the thickness of Ge-window varies with laser intensity and ambient temperature. Therefore it is suggested that this may constitute a important cause of instability of the power output, frequency and transverse...

锗窗干涉效应是造成CO_2激光器输出不稳定的一个重要因素.锗窗的两平行表面构成法布里一珀罗干涉器,其透射率与厚度有极敏感的依赖关系,而厚度又易因激光强度、环境温度等而改变,这样锗窗本身就构成了激光器输出功率、振荡频率、横模结构不稳定的重要因素.
