报告摘要：

  One difficulty in the numerical simulation of lasers is the simulation of the optical wave of the laser resonator, which satisfies Maxwell's equations or Helmholtz equation. Since the Helmholtz equation is not positive definite, a standard finite element discretization cannot be applied in case of long laser resonators. To circumvent this problem, we present a suitable new finite element discretization for long laser resonators. This discretization is based on a two wave eigenvalue model for laser resonators. Theoretical and numerical results of this discretization and the eigenvalue problem are presented.
