The temporal shape (rise time, fall time, skewness) of 50-200-fs Ti:sapphire laser pulses has been controlled by appropriate adjustment of a grating-pair compressor. It was found that the skewness of the laser pulse envelope is particularly sensitive to the third-order component of the spectral phase. Introducing such a third-order phase offset by detuning the grating pair relative to the optimum pulse compression settings allowed the generation of skewed pulses. As an example of an application, these skewed pulses were used to optimize a laser-plasma electron accelerator.
通过对光栅对压缩器进行适当调整，控制了50 - 200飞秒钛宝石激光脉冲的时间形状（上升时间、下降时间、偏斜度）。发现激光脉冲包络的偏斜度对光谱相位的三阶分量特别敏感。通过相对于最佳脉冲压缩设置失谐光栅对来引入这种三阶相位偏移，从而产生了偏斜脉冲。作为应用示例，这些偏斜脉冲被用于优化激光 - 等离子体电子加速器。
