磁场辅助的激光感生圆二色性滤波技术研究

In this paper a magnetic field assisted atomic line filter based on laser induced circular dichroism was reported. All of the atomic optical filters of laser induced circular dichroism that were previously reported adopted one beam of pumping light to couple degenerate magnetic energy level in the absence of a magnetic field. Based on this, magnetic field was added to generate the Zeeman splitting, in order to obtain a stronger tuning capability and a larger wavelength selection range. By simulation calculation, The particle number distribution under the influence of magnetic field was calculated using the rate equation, and the performance of the filter effect of the magnetic field in the various conditions was discussed.
