Abstract
The experiment of MOPA (Master-Oscillator-Power-Amplifier) laser System with an optical fiber as the phase conjugate mirror is introduced. The output laser beam from the unidirectional ring resonator was amplified and coupled in an optical fiber. We got 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 M2 is in the range of 1.1 to approximately 1.6.
