Annotation

In this paper we obtain approximate equations that describe the dynamics of a fiber optic laser with an external reflector, constructed on the basis of microresonance structures under inhomogeneous pumping conditions. The results demonstrate the possibility of the existence of selfmodulation modes with frequencies equal to the frequency of natural vibrations of the microresonator structure. The parameter ranges in which self-oscillations are possible are calculated.
