双池布里渊放大器中Stokes波的高效放大

Effectively amplification of Stokes wave in double Brillouin cell

微小Stokes信号光在布里渊放大器中得到放大 ,当Stokes信号光强度为 0 .15mJ时 ,增益系数达到 6 7。Stokes光增益决定于Stokes信号光强度及放大池中泵光与Stokes光的耦合程度 ,小信号Stokes光将得到较大的增益 。

Stokes wave amplification in double Brillouin cell has beed investigated. The experimental results shows that the gain is determined by the intensity of input Stokes signal and the coupled case with the pump beam. The gain factor of 67 and the better phase conjugation are obtained when the input Stokes intensity is 0.15mJ and at the optimum coupled case.
