| Abstract: | 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. |
