摘要：

A method to compensate phase detuning, which will lead to the low efficiency in noncollinear Brillouin amplification by controlling the frequency shift of Stokes seed, is proposed. The efficiency of noncollinear Brillouin amplification can be sustained at the level of collinear Brillouin amplification for a large crossing angle. For crossing angles between Stokes and pump of 20 degrees and 35 degrees, the Brillouin gain coefficient is improved 1.24 and 4.93 times, accordingly. (C) 2014 Optical Society of America
