Abstract: We present a numerical analysis, modeling the behavior of a Hybrid Stable-Unstable Resonator (HSUR) in strongly non-confocal configurations. The simulation outputs enable us to attest the extracted beam properties observed in our experiments on a Diode Pumped Ceramic Nd:YAG laser equipped with a non-confocal HSUR. Beam structure and propagation factor M2 are calculated and compared to the experimental measures. The parametric study of cavity losses and extracted beam properties also demonstrates that out-coupling coefficients compatible with design requirements and good quality extracted beams can be obtained also in this non-canonical cavity setup.
