Abstract
The aim of this work is to investigate theoretically the dynamical characteristics of Nd:LiNbO/sub 3/ waveguide lasers. A novel theoretical model to describe the laser dynamics has been developed and implemented; it has the capability to take into account the transversal dynamics of the population inversion, represented with a transversal orthogonal function expansion, and the longitudinal gain saturation effects due to the pump absorption and to the population inversion dynamics. The Nd-doped LiNbO/sub 3/ waveguide laser has been considered pumped in the 814 nm wavelength region. The model has been compared with the available experimental data. Results are presented in various operation conditions.
