摘　　要：根据信号波和闲频波所满足的耦合非线性薛定谔方程,导出了双抽运参量放大增益系数g、信号波的放大因子和闲频波转换效率,并在输入总抽运功率不变的情况下,仅改变双抽运功率P1,P2的比值s,对参量放大增益系数g、信号波的放大因子和闲频波转换效率理论研究和数值模拟;数值模拟结果表明:相位匹配务件下,通过改变双抽运功率的比值s=P_1/P_2,可获得适当的放大的信号波和一定转换效率的闲频波.The nonlinear coupled-mode equation base on signal wave and idler wave, the parametric amplification gain coefficient , the signal wave amplification factor and the idler wave conversion efficiency have been obtained about double pumped parametric amplification. The parametric amplification gain coefficient , the signal wave amplification factor and the idler wave conversion efficiency have been studied and numerical simulation only to change the double-pump power ratio of s = P1/P2 when the total input pump power remains unchanged. The results show that signal wave amplification and idler wave can been obtained by changes double pumped power ratio values under phase matching.
