Coherent Combining of Two Beams Based on Polarization Phase Locking

Polarized beam coherent combination of pulsed fiber laser is studied. The self-organizing passive phase lock of multilevel high power Yb-doped fiber amplifiers is achieved with optical feed-back ring cavity. Polarized beam coherent combination and multi-channel beam coaxial output are realized by using cascade polarized combining configuration. Polarized beam coherent combination of four Yb-doped fiber amplifiers is experimentally demonstrated, The efficiency of coherent combination is up to 91.9%. Stable combination pulsed fiber laser with temporal and spatial characteristic is achieved. This approach provides a feasible technique for power scaling of high-power pulsed fiber laser.
