Controlling the orientation of polar molecules with combined electrostatic and pulsed, nonresonant laser fields

Phys Rev Lett. 2003 Feb 28;90(8):083001. doi: 10.1103/PhysRevLett.90.083001. Epub 2003 Feb 25.

Abstract

We demonstrate that molecules with a moderate permanent dipole moment can be oriented with combined electrostatic and pulsed, nonresonant laser fields. We use OCS molecules as a sample. The degree of orientation can be increased by increasing the magnitude of electrostatic field and the peak intensity of the laser field or by decreasing the rotational temperature of the molecules.
