A linear polar molecule in a two-color laser field: a symmetry analysis
Mellado-Alcedo, David; Quintero, Niurka R.; González-Férez, Rosario (IOP Publishing: Conference Series, 2020)We describe the field-dressed rotational dynamics of a linear polar molecule in a a non-resonant two-color cw laser field, and analyze the orientation and alignment as the field parameters are varied.
