Strehl ratio and optimum focus of high-numerical-aperture beams [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2007
We analytically calculate the focus setting for a beam with a high numerical aperture (NA) that optimizes its Strehl ratio in the case of small aberrations up to the ’just’ diffraction-limited value (Strehl ratio ≥0.80).
