我们证明，具有中等永久偶极矩的分子可以通过静电和脉冲非共振激光场的组合进行定向。我们使用 OCS 分子作为样本。可以通过增加静电场的大小和激光场的峰值强度或通过降低分子的旋转温度来增加取向程度。
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.
