摘要
介绍了采用光纤作为位相共轭镜应用于 MOPA(Master- Oscillator- Power- Amplifier)系统的初步实验 ,利用单向环形腔振荡器输出并经一级放大 ,将放大后输出激光耦合到光纤中获得了位相共轭激光输出。当重复频率在 1～ 30 Hz变化时 ,远场发散角为 0 .6～ 0 .9mrad,相应的 M2数在 1.1～ 1.6之间变化。
The experiment of MOPA (Master Oscillator Power Amplifier) laser system with an optical fiber as the phase conjugate mirror is reported. The laser beam from the unidirectional ring resonator was amplified and then coupled in a optical fiber to get the phase conjugate beam. When the repetition rate varied from 1 to 30 Hz, the far field divergence varied from 0.6 to 0.9 mrad, and the corresponding M 2 is in the range of 1.1~1.6.
