椭圆偏振行波的磁光共振特性
Features of Magneto-Optical Resonances in an Elliptically Polarized Traveling Light Wave
摘要:
本文研究了Hanle位形中非线性吸收磁光共振参数随光波椭圆率的变化。已经发现,这些参数(振幅、宽度和幅宽比)强烈地依赖于光波的偏振。特别地,当偏振从线性改变到最佳椭圆时,谐振幅度可以增加超过一个数量级。已经表明,这种效应与气体中原子的多普勒频移有关。理论结果已在Rb蒸气中得到证实。
英文摘要:
The parameters of nonlinear absorption magneto-optical resonances in the Hanle configuration have been studied as functions of the ellipticity of a traveling light wave. It has been found that these parameters (amplitude, width, and amplitude-to-width ratio) depend strongly on the polarization of the light wave. In particular, the resonance amplitude can increase by more than an order of magnitude when the polarization changes from linear to optimal elliptic. It has been shown that this effect is associated with the Doppler frequency shift for atoms in a gas. The theoretical results have been corroborated in experiments in Rb vapor.
