Abstract

For analyzing the properties of a laser, it is helpful to calculate the eigenmodes of the laser cavity. A new approach for modeling these eigenmodes is to approximate them by a finite element discretization of a 3D two-wave eigenvalue problem. In this paper, we analyze the properties of this model. First, we show that the two-wave eigenvalue problem is equivalent to an Helmholtz eigenvalue problem. Second, we analyze the stability of the finite element discretization and explain how to construct a suitable iterative solver. Numerical results are presented.
