Abstract

This paper applies a body-of-revolution finite-difference time-domain technique for simulating the focusing of ultrashort, pulsed beams using a thin dielectric lens. A numerical analysis is presented and results compared to those obtained from approximate analytical models, both of which show that the pulse rise time is of critical importance in the process of focusing. For the case of ultrawide-bandwidth (UWB) pulses it is seen that intensity is enhanced over that obtained from continuous-wave (cw) results.
