RbHe和RbN $_2$分子的圆二色性
Circular Dichroism of RbHe and RbN$_2$ Molecules
摘要：
我们提出了测量的圆二色性的光泵Rb蒸汽附近的D1共振线。与缓冲气体$^3$ He和N $_2$的碰撞降低了蒸汽的透明度，即使在完全极化时也是如此。我们使用两种方法来测量这种效果，表明他的结果可以从RbHe势曲线来理解，并显示这种效果如何与光泵浦光的光谱分布合谋，以增加非常光学厚的样品的光泵浦的激光功率需求。
英文摘要：
We present measurements of the circular dichroism of optically pumped Rb vapor near the D1 resonance line. Collisions with the buffer gases $^3$He and N$_2$ reduce the transparency of the vapor, even when fully polarized. We use two methods to measure this effect, show that the He results can be understood from RbHe potential curves, and show how this effect conspires with the spectral profile of the optical pumping light to increase the laser power demands for optical pumping of very optically thick samples.
