我们提出了一种简单的方法来压缩二次谐波产生的光脉冲。非周期准相位匹配光栅使二次谐波脉冲相对于基脉冲产生频率相关的相移，并可用于校正任意相位畸变。讨论了其产生机理，并对二次相位（线性频率）啁啾脉冲的压缩进行了详细的分析。
We propose a simple means for compressing optical pulses with second-harmonic generation. Aperiodic quasi-phase-matching gratings impart a frequency-dependent phase shift on the second-harmonic pulse relative to the fundamental pulse and can be engineered to correct for arbitrary phase distortions. The mechanism is discussed, and a detailed analysis of the compression of quadratic phase (linear frequency) chirped pulses is presented.
