摘要：

We simulated the amplification process during the broadband optical parametric amplification, and we proposed an improved design for high conversion-efficiency during broadband optical parametric amplification based on our simulation result. We carried out an experimental research based on our design. After our research on the key technologies, such as spatial shaping, temporal shaping, superfluorescence suppression, bandwidth matching, we increased the conversion efficiency with suppression of the superfluorescence. The conversion efficiency with our one-stage optical parametric amplification could reach 30%.
