Energy characteristics of laser with saturable anisotropic absorbing medium in cavity

The single-frequency steady-state lasing mode of a laser in which the cavity contains an absorbing medium in the longitudinal magnetic field and elements that create circular phase and linear amplitude anisotropy is investigated theoretically. The influence of various factors on the size of the losses introduced in the laser cavity by the absorbing medium, and the corresponding changes in the intensity of the radiation generated at the frequency of the absorption line, are investigated. The relative change in the absorption lines when a magnetic field is applied to the absorbing medium is calculated as a function of the lasing intensity in the absence of absorption in the cavity. The analytical data show good agreement with experimental values. The findings can be utilized for intracavity laser spectroscopy.
