| Abstract: | 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 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 |
