N2 - We consider a system of coupled Raman fiber lasers which exhibit PT-symmetric or PT-broken symmetry properties depending on phase shifts between coupled cavities and pump power. We numerically study temporal properties of radiation of this system. We found that besides laminar and turbulent generation regimes of different PT-properties, the coupled lasers allows generation of pulses. The pulsed generation properties are varying from noise-like pulses to stable hundreds of ps-scale pulses depending on pump power and PT-symmetry of the system. We track the transitions between different pulsed regimes and also found that these regimes could co-exist at the same time.
