Field-free molecular orientation steered by combination of super-Gaussian and THz half-cycle laser pulses Project supported by the National Natural Science Foundation of China (Grant Nos. 11674198 and 11874241) and the Taishan Scholar Project of Shandong Province, China. |
(a) Time evolution of molecular orientation induced by THz HCP (black dot), super-Gaussian pulse (red dash), and combination of THz half-cycle and super-Gaussian pulses (olive solid). (b) Time-dependent population of J = 0 to 5 states in panel (a). |
