Selection of right-circular-polarized harmonics from p orbital of neon atom by two-color bicircular laser fields |
Harmonic spectra from the initial state p+ (left column) and p− (right column) states. The red solid line and the blue dashed line represent the x component and the y component, respectively. (a) and (c) 30th–90th orders. The insets show the overlook of the whole harmonic spectra structure. (b) and (d) The phase differences between x and y components. The red solid circles and the blue solid squares represent 3n+1 and 3n+2 orders, respectively. The parameters of the two laser pulses are |
