| 摘 要： | 实验研究了注入控制对铜蒸气激光非稳腔输出光束质量的影响，从输出光发散角时间分辨过程的测量结果说明注入加速被注入腔内激光发散角的减小过程。由于被注入腔内放大自发辐射的存在，为得到较好的注入控制效果，注入光的脉宽和进入被注入腔的延时必须恰当。

| Abstract: | The beam quality of an unstable resonator copper vapor laser with injection controlling has been studied experimently. Measurement results of the time resolved beam divergence shows that the injected signal accelerates the improvement course of unstable resonator output. Because of the exist of amplified spontaneous emission, when the injected beam is near the diffraction limit, the pulse width of the injected laser and delay time must be appropriate for obtaining ideal output performance. |
