Effect of refractive index mismatch aberration in arsenic trisulfide

Cumming, Benjamin P; Debbarma, Sukhanta; Luther-Davies, Barry; Gu, Min


We demonstrate compensation for the spherical aberration due to the refractive index mismatch that occurs when a laser beam is focused into a thick arsenic trisulfide (As -2 S -3 ) film with a high numerical aperture objective. The effects of the aberration at different focal depths on the point spread function have been calculated numerically and the axial response method shown to be a useful measure for compensating the spherical aberration. We show that with the addition of adaptive optics...[Show more]
