abstract = "We numerically consider the system of coupled Raman fiber lasers which depending on the phase shifts between coupled cavities can be operated either in PT-symmetric or PT-broken generation regime. Within the full dynamical model of coupled NLSE we plot the generation properties map over phase shifts and pump powers. We found different types of the generated radiation in both PT-symmetric and PT-broken phase: quasi-CW stochastic generation, generation of noise-like pulses, and stable pulsed generation of narrow pulses of 100-200 ps width. We also reveal transitions between different generation states and types of the radiation over pump power and/or phase shifts between coupled cavities. In addition, we determined the optimal parameters of a system of coupled Raman fiber lasers to achieve pulsed lasing depending on the lasing regime with respect to PT symmetry.",
