数值模拟结果表明，在具有光学非线性和群速度色散的拟周期极化介质中，两个飞秒近红外脉冲的差频混合过程中，中红外脉冲是任意形状的。形状脉冲包括线性啁啾脉冲和脉冲串，具有很高的转换效率。
Numerical simulations demonstrate that mid-infrared pulses are arbitrarily shaped during the differential frequency mixing of two femtosecond near-infrared pulses propagating in an engineered quasi-periodic poled medium with optical nonlinearity and group velocity dispersion. Shaped pulses, including linearly chirped pulses and pulse trains, are generated with high conversion efficiencies.
