Abstract

We theoretically propose two-color laser manipulation with greatly improved efficiency to mechanically manipulate single organic molecules. The present method is based on the nonlinear resonant laser manipulation proposed in a recent study. In the first part, we describe a method to trap single organic molecules that can be more effective than ever before utilizing two-color beams. In the second part, we demonstrate the possibility to selectively “pull” single organic molecules with a particular type of electronic-level scheme by using single-side illumination of traveling light.
