Abstract
The eigenmodes of a resonator with misaligned rooftop mirrors are circular right or left polarized waves which have different resonant frequencies. We discuss effects of the frequency pulling and polarization behavior of the output of the methanol model laser with a three-level homogeneously broadened amplifying medium with rooftop misaligned resonator as a function of the pump intensity and the parameters of the resonator. We show the possibility of a constant in time output of the rooftop laser with its each linearly polarized component modulated in time with a frequency equal to the beat frequency of the Stark -- splitted components of the laser- active transition line. The electric strength vector of the output radiation in this case rotates in time with the beat frequency.
