摘要
A new fast dynamic model for TMI investigation is presented and used to study the evolution of the internal powers, inversion and thermal gratings and the impact of relative phase shifts on the amplifier dynamics, showing the prevalence and importance of nonlinearly-induced beat-length variations. The optical field is represented in a modal basis, with overlaps with thermal field components precomputed. This allows optical propagation to be achieved with an efficient Runge-Kutta scheme, with mode coupling represented by a coupling term. This substantially reduces the computational load of the simulation. New features of TMI dynamics are revealed.
