title = "New multipass superposition modes and universal instabilities in axially pumped solid-state lasers",
abstract = "We propose a laser eigenmode must be represented as the superposition of consecutive multipass Gaussian modes and new universal instabilities when pumping beam size is less than bare cavity beam size in specific degenerate configurations. It exhibits multiple focii when it images by a lens in free-space. This laser eigenmode has lower threshold and lower slope efficiency. The laser develops into instabilities that correspond to discontinuity in the transverse-mode profile is subject to transition between single-pass transverse mode and multi-pass transverse mode. The multipass transverse modes and instabilities are experimentally observed in a tightly focused pumped Nd-YVO4 laser.",
