“…Passive CBC relies on self-phase locking via passive coupling mechanisms to combine lasers coherently, which has simple and stable configuration. There are many reports on passive phase-locked techniques such as self-Fourier laser cavity [9,10] ,self-organization mutual injection locking lasers mechanism in fiber laser arrays [11,12,13] and optical feed-back ring cavity [14][15][16][17][18][19][20][21] .The highest output power 1090W of passive coherent beam combination is obtained with optical feed-back ring cavity [21] .However, the research of CBC is mainly focus on CW fiber laser, CBC of pulsed fiber laser is more complicated owing to the difficulty of in-phase detection and controll [22,23] .…”

Self-organized passive coherent beam combination of multichannel pulsed laser with all-fiber configuration is reported. The phase of multichannel Yb-doped pulsed fiber amplifiers is locked by optical feed-back ring cavity. The traditional disadvantage of energy dissipation to side lode for lower aperture filling is solved via all-fiber laser array with single-aperture configuration. Coherent beam combination of four pulsed fiber amplifiers is experimentally demonstrated. Variable pulsed laser can be obtained by adjusting a AOM,stable combination pulsed fiber laser with excellent temporal and spatial characteristic is achieved. The efficiency of coherent combination is up to 85.0%. This approach presented here provides a feasible technique for power scaling of high-power pulsed fiber laser and maintaining beam quality simultaneously.

We present an approach for effectively combining high-power pulsed lasers based on a refraction displacement pulse combining technique. This approach allows for lasers combining with various repetition rates, pulse duration, polarization, output power, and wavelength. The maximum number of lasers that can be combined mainly depends on their repetition rate and pulse duration. This approach is a feasible way to combine a large number of high average power lasers while maintaining good beam quality.

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.
