Abstract:
The behavior of the gain of dye lasers with polarization anisotropic cavities is theoretically investigated. In the stationary approximation, the spectral and polarization characteristics of the gain are calculated for two regimes of laser operation: with broadband and narrow-band cavities. It is shown that gain anisotropy of linearly polarized radiation is frequency dependent, that is, it exhibits dichroism. It is established that this effect is caused by the overlap of the dye emission and absorption bands and depends on the laser parameters: pumping rate and Q-factor of the cavity. In addition, for a narrow-band tunable laser the dependence of dichroism of the gain on the tuning frequency has been established.
