| 摘 要： | 通过对薛定谔方程的数值解,给出了扫频脉冲光场对四能级原子系统作用的结果,说明了扫频脉冲光场应用于高斯分布的多普勒加宽原子统计系统,在适当的扫频条件和激光功率下能得到比单色或调幅脉冲光场更有效的三步光电离。

| Abstract: | Through numerical solution of the Schrodinger equation we illustrate the effects of frequency modulation laser upon the excitation of a four-level system irradiated by simultaneous laser pulse. When the laser power is sufficiently great and the frequency modulation parameters are suitable, it shows that the frequency modulation excitation applied to a Gatlssin statistical distribution of detunings can obtain more effictive three-step photoionizatioa than monochromatic or amplitude modulation excitation does. |
