利用相位啁啾单色中红外激光场产生高次谐波
High－order harmonic generation with single mid－infrared laser field by a phase－chirping
摘要
Abstract
By solving the time－dependent Schr?dinger equation,we present a theoretical investigation of high－order harmonic and isolated attosecond pulse generation in infrared laser field with phase chirping.It is demon-strated that the yield of the supercontinuum harmonic can be increased and ultroshort isolated attosecond pulse can be obtained by phase chirping.Especially,by the phase of 0.3 πand β＝0.3 in βt,the bandwidth of 822 eV of harmonic spectrum and an isolated 2.7 as pulse can be obtained.Meanwhile,the conversion efficiency of harmonic and intensity of isolated attosecond pulse can be enhanced effectively.关键词
