Effects of Pulse-shape on High Order Harmonic Generation of Hydrogen Atom
脉冲形状对氢原子高次谐波的影响

The high order harmonic generation(HHG) of hydrogen atom radiated by ultra-strong femto-second laser pulse was simulated by the TDDFT method with the classical and quantum combination technique.And the effects of pules-shape on HHG were studied.The results indicate that the HHG spectrum of hydrogen atom is similar to the typical atom HHG spectrum,which have a Decrease-Plateau-Cutoff structure.A kind of odd allowed,even forbidden selective phenomena of the order number of HHG are observed.The different pulse...
