摘要

Coherent control of molecular alignment and orientation remains a field of growing interest with open questions coming from both the experimental and theoretical points of view due to its widespread applications in areas such as the alignment dependence of multiphoton ionization,[1-3] molecular frame photoelectron angular distribution,[4-6] laser-induced diffraction,[7] molecular imaging,[8-10] high-order harmonic generation,and at tosecond science.[11,12] Alignment refers to the confinement of molecule-fixed axes along laboratory-fixed axes,and orientation refers to the molecular dipole moment pointing in a particular direction.[13,14] Field-free molecular alignment has been used to manipulate the femtosecond pulse compression,[15] to generate few-cycle pulse generation,[16] to measure ultrashort laser pulses based on the M-XFROG,[17-19] and to modulate THz generation.
