Abstract :
The aim of this work is to investigate theoretically the dynamical characteristics of Nd:LiNbO3 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 LiNbO3 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
