Abstract:

Comparing to the accurate model of FADOF, the energy level of the strong field model is simple, so it can be used to give some analytical expressions. But it is only valid when the magnetic field is strong. By solving the transmission spectrum of the FADOF for the sodium D2 transition by these two models. And testing these results by the experimental data, applying condition for the strong-field model is successfully found. When the magnetic field is less than 0.1 T, the transmission spectrum difference of these two models is greater than 50%, and when the magnetic field is greater than 0.3 T, the difference is less than 5%.

Key words: spectroscopy, applying condition of the strong-field model, model comparison method, Faraday anomalous dispersion optical filter, lidar
