Paper Abstract

We present the results of a simulation program able to describe the dynamics of a Nd:MgO2:LiNbO3 P.E. waveguide laser. A special feature of this simulator is the ability to take into account the spatial hole burning effect on the population inversion in the transverse directions and the time modulation of the pump absorption due to the population inversion dynamics. Modal pump and signal waveguide fields and population inversion are expanded using Gauss-Hermite functions in the lateral direction and generalized Laguerre functions in depth. Only one function is used to represent the pump and the lasing fields and a maximum of eight functions in lateral and eight in depth direction to represent the population inversion. The need of this accurate modeling is shown by comparison with the results of a simplified model.
