据我们所知，我们提出了一种生成可调谐窄带宽皮秒脉冲的新方法，其中通过差频混合来消除等拉伸泵浦和信号的啁啾。分析了群速度失配对输出脉冲带宽的影响。通过在 I 型 β 硼酸钡晶体中从 1-ps 脉冲开始生成 3.3-cm-1 带宽和 10-ps 持续时间的脉冲，对该方法进行了实验证明。
We propose what is, to our knowledge, a novel method of generating tunable narrow-bandwidth picosecond pulses in which the chirp of equally stretched pump and signal is canceled by difference-frequency mixing. The effect of the group-velocity mismatch on the output pulse bandwidth is analyzed. The method is proved experimentally by generation of pulses of 3.3-cm-1 bandwidth and 10-ps duration in a type I β barium borate crystal, starting from 1-ps pulses.
