| مستخلص: | The transverse structures of geometric modes in degenerate laser resonators with large astigmatism are systematically investigated by starting from the Gaussian wave packet formulation with ray-wave connections. The overlapping degree $D$D between Gaussian wave packets is derived as an analytic expression that manifests the critical overlapping with ${\boldsymbol D} = 1$D=1. The transverse patterns are confirmed to display a structure of continuous curves or dotted spots, depending on ${\boldsymbol D} \gt 1$D>1 or ${\boldsymbol D} \lt 1$D<1, respectively. A thorough comparison between experimental results and numerical calculations is performed to validate the theoretical analysis. |
