Helicoid modal analysis of laser oscillators with spherical aberration.
A technique for the modal decomposition of laser beams allows an analysis of laser oscillators perturbed by rod spherical aberration. Beam quality can be degraded or improved, depending on whether the beam scale increases or decreases with lens power. Efficient power extraction is problematic, however.
