ABSTRACT:
The purpose of the nonlinear spectrophotometer is to provide a simple instrument that can be used on a routine basis to accurately measure the two-photon absorption (TPA) coefficient and cross-section on a wide variety of materials. The instrument is capable of measuring: (1) both organic and inorganic materials, (2) solutions and thin film materials forms, and (3) materials which are fluorescent and nonfluorescent.
