摘要

Numerical model of fiber laser is proposed suitable for numerical investigation of fiber laser dynamics. The model is based on the equations describing propagation effects, linear coupling of oppositely running pulses and its interaction in a ring or standing-wave fiber cavity. The derivation of these equations is based on the field representation in terms of longitudinal harmonics rather than monochromatic waves. This allows to formulate easily the initial values problem for numerical simulations, to the contrast to two-points boundary values problem in the case of monochromatic wave decomposition. Numerical results are presented for the case of Raman pump by CW monochromatic laser radiation using upwind method. The results can be applied for investigation of dynamics in fiber lasers, including Raman lasers, especially with long cavities, and random feedback fiber lasers.
