关于显著提高$^{87}$ Rb的D1线暗共振对比度的唯一可能性
On the unique possibility to increase significantly the contrast of dark resonances on D1 line of $^{87}$Rb
摘要：
提出并实验研究了在激发态光谱分辨条件下，双色线偏振光（{ \em lin} $||$ { \em lin}场）激发核自旋为$I=3/2$的Alakli原子D1线相干布居俘获共振的新方案.该方案的独特性质导致了$^{87}$ Rb的D1线暗共振的高对比度。
英文摘要：
We propose and study, theoretically and experimentally, a new scheme of excitation of a coherent population trapping resonance for D1 line of alakli atoms with nuclear spin $I=3/2$ by bichromatic linearly polarized light ({\em lin}$||${\em lin} field) at the conditions of spectral resolution of the excited state. The unique properties of this scheme result in a high contrast of dark resonance for D1 line of $^{87}$Rb.
