论文摘要
我们认为光学偶极势能是由两级原子与小腰部圆形极化的拉瓜仪激光束相互作用产生的。梁的特征是存在纵向电场成分,该纵向电场成分负责在光学偶极子势能中出现手性项。该术语会逆转符号,如果绕组的绕组数或梁的波偏振反向符号。我们提出了与两级原子的双重涡流相互作用的方案,其中所得的光学偶极电位是完全手性的。
We consider the optical dipole potential energy, which arises from the interaction of a two-level atom with a circularly polarized Laguerre-Gaussian laser beam of small waist. The beam is characterized by the existence of a longitudinal electric field component which is responsible for the appearance of a chiral term in the optical dipole potential energy. This term reverses sign if either the winding number or the wave polarization of the beam reverses sign. We propose a scheme of a bi-chromatic vortex interaction with the two-level atom in which the resulting optical dipole potential is fully chiral.
