摘要: 报道了轴对称-折叠组合腔CO2激光器原理性实验研究，激光器能在CW模式下成功运行。研究得到了激光器最佳的气体比率和气体压强。通过研究CO2激光器的不同方面，如激励门电压和输出功率等，发现它们随着放电电流的变化而变化。通过实验得到了激光光束的光斑和聚焦的实验光斑，并模拟了光强分布。激光器已经成功的组建、运行和调试，获得的最大输出功率为58 W。Abstract: This paper reports the experimental investigation on the principle of axisymmetric-fold combination CO2 laser. The laser operated successfully in CW mode. The optimum gas mixture ratio and the gas pressure of the laser were determined. Different aspects of the CO2 laser were studied including the variations of excitation threshold voltage and output power with discharge current. The output spots and the light intensity distribution of the laser beam were obtained. The convergence of the laser beam was performed through an optical imaging system. The laser was successfully constructed, operated and tested for different applications within the limits of its maximum output power of 58 W.
