基于双光泵浦的原子光学滤波器

In this paper an atomic filter based on laser induced circular dichroism and with two beams of pumping light was reported. All of the atomic optical filters of laser induced circular dichroism that were previously reported adopted one beam of pumping light to make the atomic population stay in particular excited states. Based on this, a beam of re-pumping light was added and it was used to drive the specially appointed energy level transition. By simulation calculation, feasibility of the re-pump light was discussed employing the rate equation, and contribution of re-pumping effect to the transmission was discussed under various conditions.
