Abstract
We present a theoretical study on polarization rotation and transmission spectroscopy where the co-propagating probe and coupling beams are linearly and circularly polarized, respectively. We calculate the spectra by using three methods; calculations using the density matrix equations (i) with and (ii) without wave-mixing, and (iii) calculations using the rate equations. We found that to find the spectra with the coherences neglected, the calculations had to be performed using the density matrix equations without wave-mixing rather than the rate equations.
