Abstract: The development history of nonlinear optics laser beam combining technology is reviewed. The basic principles and beam combining ideas based on optical phase conjugation and nonlinear amplification process are expounded. The landmark achievements of laser beam combining methods involving the overlapping coupling, the seed injection and the Brillouin four-wave mixing enhanced phase locking are sorted out. The advantages and bottlenecks of plasma cross beam energy transfer, diamond Raman amplification and liquid Brillouin amplification laser beam combining technologies are summarized. Facing the requirements for realizing high peak power, high average power and high repetition rate laser output, based on the advantages of simple system structure, high power load and high heat dissipation efficiency of the Brillouin amplification laser beam combining technology, we proposed a feasible scheme of the combining laser output with pulse energy of 100 J, pulse width of 10 ns, and repetition rate of 10 Hz.
