Field-free molecular orientation by delayed elliptically polarised laser pulses

The figure shows the probabilities of the magnetic levels as a function of elliptic parameter a2 of the delayed pulse, having non-zero values for the rotational state J = 3 for a pulse pair of SSQR-SSQR type with a delay of 1.9 ps. The elliptic parameter a1 of the initial pulse is equal to 0.5. The pulse widths are 1.0 ps and the field strengths are equal to 7.3 MV/cm. 82
