Interference effect of photoionization of hydrogen atoms by ultra-short and ultra-fast high-frequency chirped pulses |
The survival of initial ground state hydrogen atoms in the presence of strong laser pulses with different intensities. In this case, we take the carrier frequency ω0 = 53.605 eV, and the pulse duration τ0 = 6 fs. Different color and line styles denote the corresponding results in different gauges. |
