Abstract

An optical resonator with holes on-axis for applications in an FEL oscillator was recently proposed by Pantell et al. These authors presented an analytical approach based on approximating the field inside the resonator by a truncated expansion in Gauss-Laguerre modes. We perform further investigation of this configuration by using a Fox and Li type code which was recently applied to the analysis of a laser resonator with internal circular aperture. This numerical approach allows us to check the range of validity of Pantell's solutions, the parameters for which they constitute the lowest-loss mode and to map the transverse profile of the mode at different planes inside the resonator.
