对 Ca 的自电离态 (AIS) 附近的激光诱导连续谱结构的电离和三次谐波产生进行了实验研究。结果表明，诱导结构的形状受到 AIS 存在的强烈影响，并且表现出从窗口共振下降到峰值的失谐和激光强度依赖性转变。观察到的连续体的修改是根据干扰激励通道进行讨论的。
Experimental investigations of the laser-induced continuum structure in the vicinity of autoionizing states (AIS’s) of Ca are reported for both ionization and third-harmonic generation. The shape of the induced structures is shown to be strongly affected by the presence of the AIS’s, as well as exhibiting a detuning-and laser-intensity-dependent transition from a window resonance dip to a peak. The observed modification of the continuum is discussed in terms of interfering excitation channels.
