铅原子非共振多光子电离过程的研究

Investigation of nonresonant multiphoton ionization process of lead atoms

在激光波长为1064nm、532nm和355nm下,研究了铅原子的非共振多光子过程.通过改变激光脉冲的线宽研究了铅原子非共振7-光子电离速率和激光统计性的依赖关系.

The nonresonant multiphoton ionization process of lead atoms are investigated at the laser wavelengths of 1064 nm, 532 nm, 355 nm. The dependence of the 7-photon ionization probability of lead atoms on the statistical properties of laser pulse has been analysed by varying the spectral bandwidth of the laser pulse.
