In this paper, the semi-classical theory was utilized to theoretically analyze K-532nm Laser-induced dispersion optical filter (LIDOF), and theoretical model was given. By solving the density matrix equations, the system induced polarizability was gained, and eventually the transmission spectra were gained by theoretical calculation.
A theoretical model for the Laser induced dispersion optical filter (LIDOF) is presented. The filter has a higher transmission and a narrower line width than excited-state Faraday anomalous dispersion optical-filter (ESFADOF). The theoretical treatment is valid for different atoms LIDOF systems.
