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. |
Maximum degrees of the positive (blue square) and negative (red circle) orientation ⟨cosθ⟩max versus time delay td. The green dashed curve refers to the molecular orientation varying with time by a super-Gaussian pulse only. |
