| 中文摘要 | the characteristics of backward harmonic radiation due to electron oscillations driven by a linearly polarized fs laser pulse are analysed considering a single electron model. the spectral distributions of the electron's backward harmonic radiation are investigated in detail for different parameters of the driver laser pulse. higher order harmonic radiations are possible for a sufficiently intense driving laser pulse. we have shown that for a realistic pulsed photon beam, the spectrum of the radiation is red shifted as well as broadened because of changes in the longitudinal velocity of the electrons during the laser pulse. these effects are more pronounced at higher laser intensities giving rise to higher order harmonics that eventually leads to a continuous spectrum. numerical simulations have further shown that by increasing the laser pulse width the broadening of the high harmonic radiations can be controlled. |
