使用超快分子相位调制方法生成了持续时间低于 4 fs 的脉冲。比分子振动或旋转周期短的激光脉冲在沿着填充有先前脉冲激发的拉曼活性气体的中空波导传播期间获得光谱展宽。通过改变分子振动周期内激励和探测脉冲之间的延迟，可以控制感应的时间相关相位、频率和频率啁啾。
Pulses with durations below 4 fs have been generated using the method of ultrafast molecular phase modulation. A laser pulse shorter than the molecular vibrational or rotational period obtains spectral broadening during propagation along a hollow waveguide filled with previously impulsively excited Raman active gases. The induced time dependent phase, frequency, and frequency chirp are controllable by changing the delay between excitation and probe pulse within the molecular vibrational period.
