| 中文摘要 | the dynamics and harmonics emission spectra due to electron oscillation driven by intense laser pulses have been investigated considering a single electron model. the spectral and angular distributions of the harmonics radiation are numerically analyzed and demonstrate significantly different characteristics from those of the low-intensity field case. higher-order harmonic radiation is possible for a sufficiently intense driving laser pulse. a complex shifting and broadening structure of the spectrum is observed and analyzed for different polarization. for a realistic pulsed photon beam, the spectrum of the radiation is redshifted for backward radiation and blueshifted for forward radiation, and spectral broadening is noticed. this is due to the changes in the longitudinal velocity of the electron during the laser pulse. these effects are much more pronounced at higher laser intensities giving rise to even higher-order harmonics that eventually leads to a continuous spectrum. numerical simulations have further shown that broadening of the high harmonic radiation can be limited by increasing the laser pulse width. the complex shifting and broadening of the spectra can be employed to characterize the ultrashort and ultraintense laser pulses and to study the ultrafast dynamics of the electrons.
