研究了一对飞秒钛宝石激光脉冲垂直入射产生的Al等离子体中软X射线脉冲（40-100 A）的时间和光谱演化。软X射线发射和脉冲持续时间都随着预制等离子体尺度长度的增加而增加。预脉冲增强软X射线发射约100倍，脉冲持续时间为100-130 ps。光谱解析的时间历程显示，较短波长的发射开始和衰减相对较快，而较长波长的发射建立和衰减较慢。
The temporal and spectral evolution of soft x‐ray pulses (40–100 A) emitted from Al plasma produced by a pair of femtosecond Ti:sapphire laser pulses at normal incidence was studied. Both the soft x‐ray emission and the pulse duration increased with increase in the scale length of the preformed plasma. Prepulse enhanced soft x‐ray emission about 100 times with a pulse duration of 100–130 ps. A spectrally resolved time history revealed that the emission at shorter wavelengths started and decayed relatively more quickly, and emissions at longer wavelengths built up and decayed more slowly.
