Laminar and turbulent generation states of different parity-time symmetry properties in coupled Raman fiber lasers

Research output: Chapter in Book/Report/Conference proceedingConference contributionResearchpeer-review


Raman fiber lasers are known for a various types of generation regimes based on their stochasticity properties. Usually, Raman fiber lasers generate in so-called turbulent generation regime characterized by almost stochastic temporal dynamics and wide generation spectrum. However, under specific conditions, one can achieve a so-called laminar generation regimes with largely suppressed temporal intensity fluctuations and narrow generation spectrum consisting of highly correlated longitudinal modes. From other side, by an introducing a concept of PT-symmetry, one can achieve generation regimes different by their parity-time-symmetry properties. In coupled Raman fiber lasers PT-symmetry could be introduced as well. In this manuscript we consider an interplay between PT-symmetric generation properties and temporal properties of the generation. We show that various turbulent and laminar generation regimes could have different PT-symmetric properties.
