Caustic effects on the high-order harmonic generation in graphene
Fulong Dong, Qinzhi Xia, Jie Liu
We employ the two-band density-matrix equations and time-dependent density functional theory to calculate high-order harmonic generation (HOHG) in graphene under a femtosecond lase…

Knee structure in the laser intensity dependence of high-order harmonic generations for graphene
Fulong Dong, Jie Liu
We investigate the high-order harmonic generations (HHGs) of graphene irradiated by linearly polarized lasers with intensities in a wide range from W/cm to W…

Classical effect for enhanced high harmonic yield in ultrashort laser pulses with a moderate laser intensity
Y. Z. Shi, F. L. Dong, Y. P. Li +2
We study the influence of the pulse duration on high harmonic generation (HHG) with exploring a wide laser-parameter region theoretically. Previous studies have showed that for hig…
