Abstract
The scheme of a bidirectional ring fiber laser with a 90° Faraday rotator in the cavity has been theoretically studied. The Faraday rotator is employed as a nonreciprocal phase element producing splitting of natural frequencies of the laser cavity modes propagating in opposite directions. The theory predicts two possible regimes of bidirectional operation. According to this, the laser generates a pair of modes propagating in opposite directions with either complex-conjugate or orthoconjugate polarization states. In the former case, the frequency shift between the modes propagating in opposite directions is independent of the reciprocal birefringence of the laser cavity and amounts to half of the free spectral band of this cavity.
