Computational Analysis of Hybrid Two-Photon Absorbers with Excited State Absorption

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathenng and maintaining tt data needed, and completing and reviewing this collection of information. AbstractThis work represents the joint work of several groups including numerical calculations and experiments. Numerical calculations were performed for the propagation of a femtosecond laser beam through an optical path and a nonlinear absorber. The results were compared with experiments performed under similar conditions. There was excellent agreement between calculations and experiments at low input energy. However, further additions must be done to the calculation of the optical path for high input energy.
