Spherical aberration in on-axis and offset unstable confocal resonators.
An analysis of spherical aberration in on-axis and offset unstable laser resonators is presented. Closed-form analytic expressions of the associated Strehl ratio as a function of cavity dimensions and magnification are derived, and effects of simple phase corrections in the optical system are assumed.
