Numerical simulations of molecular orientation using strong, nonresonant, two-color laser fields

摘要: We have investigated the possibility of molecular orientation using an asymmetric potential created by superposition strong, nonresonant, two-color (ω+2ω) laser fields. The time-independent Schrodinger equations are solved numerically for FCN molecules as example in adiabatic regime where proceeds slowly compared to rotational period molecules. show intensity dependence parameter 《cos θ》 and alignment 《cos2 θ》 θ is angle between polarization axis axis, their time evolution during fields, suggesting that our approach can be used orient polar if they rotationally cold.
