| 摘 要： | 相位匹配是实现高效光学参变啁啾脉冲放大(OPCPA)能量转换的关键之一,通过对几种常用非线性晶体的光学参变啁啾脉冲放大过程进行数值模拟研究,结果表明一定程度的相位失配不但能增加光学参变啁啾脉冲放大增益带宽,而且会使啁啾脉冲光谱强度分布中间凹陷。提出利用光学参变啁啾脉冲放大相位失配放大作为啁啾脉冲频谱整形的新方法,通过理论分析和模拟计算,找到了光学参变啁啾脉冲放大相位失配啁啾脉冲频谱整形效果的控制量;并对几种常用非线性晶体在简并、近简并、非简并等条件下的光学参变啁啾脉冲放大相位失配放大特性进行了比较。 |

| Abstract: | Phase matching is one of the important keys for high-efficiency energy conversion in optical parametric chirped pulse amplification(OPCPA).With simulation on the OPCPA process of several conventional nonlinear crystals,it is found that the spectra of output signal from phase mismatched OPCPA is broadened,and the center of spectra is depressed.It is proposed that the phase mismatched OPCPA can be a novel method for spectra shaping of chirped pulses The parameters influencing the spectra shaping process is given.The amplifying characteristics with OPCPA phase mismatching for several conventional nonlinear crystals under degenerate,quasi-degenerate and non-degenerate conditions are compared. |
| Keywords: | ultrafast optics chirped pulse spectrum shaping optical parametric chirped pulse amplification phase mismatching |
