Abstract

Oscillating-amplifying integrated fiber laser (OAIFL) can take into account the advantages of fiber laser oscillators and amplifiers, including well anti-back reflected light ability, high conversion efficiency, good nonlinear suppression capability and compact structure. In this work, based on the steady-state rate equations of the fiber laser, combined with the special boundary conditions of OAIFL, the rate equation model of the OAIFL is established. Based on this model, the effects of the pump configuration, the fiber length ratio of the oscillating section and the amplifying section, and the reflectivity of the output coupler fiber Bragg grating on the output characteristics of the OAIFL are theoretically studied. In addition, experiments are carried out to verify the reliability of the pump control logic of the laser under different pump configurations. The results show that OAIFL can maintain a safe working state when using the pump control sequence that inevitably causes laser burnout in conventional fiber laser amplifiers.
