以下为句子列表：
英文: 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
中文: 文摘: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.
