我们使用一个单一的聚焦非共振激光束测量场诱导排列的分子的偶极力的作用。我们表明，通过对齐过程中，我们可以修改的有效极化率场极化，从而控制分子的质心运动。我们观察到的CS{sub 2}分子上的偶极力的最大变化为20%时，从线偏振光改变为圆偏振光。此外，还研究了偶极力对不同振动态的影响。
We measure the role of field-induced alignment on the dipole force for molecules using a single focused nonresonant laser beam. We show that through the alignment process we can modify the effective polarizability by field polarization and thus control the center-of-mass motion of the molecule. We observe a maximum change of 20% in the dipole force on CS{sub 2} molecules when changing from linearly to circularly polarized light. Additionally, the effect of the dipole force on different vibrational states is also studied.
