| 摘 要： | 讨论了在大相位失谐下,基波为频率啁啾脉冲的二次谐波产生过程,结果表明选取合适的啁啾参量可以使二次谐波的光强提高,但同时会使其波形和相位发生变化.三波相位的畸变主要取决于入射的基波啁啾脉冲,而与相位匹配的失谐量关系不大.

| Abstract: | Temporal properties of the second ordre process with a Chirped incident pulse are theoretically calculated.The chirp influences the irradiance and the pulse shape of the second harmonic wave with large phase mismatch.The phase distortion of all three waves is dependent more strongly on the chirp than on the phase mismatch. |

| Keywords: | Second harmonic generation Chirped pulse Phase distortion |
