Split-step Fourier method for rotation-cylindrical acousto-optic interaction within the numerical aperture area

Abstract

In this paper the split-step Fourier method is used to find a solution to the rotation-cylindrical acousto-optic interaction problem. The numerical results are applied to practical examples which could help to answer the safety question during a combined application of ultrasound for selective tissue excision and Nd:YAG-laser for coagulation of bleeding tissue in surgical therapy.
