Abbreviated Journal Title
2-PHOTON ABSORPTION; SINGLE-BEAM; GENERATION; Optics
We present a technique for rapid characterization of degenerate nonlinear absorption and refraction spectra using a femtosecond white-light continuum (WLC) pulse to perform Z-scans. The spectral components of the WLC source are temporally and spatially dispersed to minimize nondegenerate two-photon absorption (2PA) processes. We demonstrate the validity of the method by measuring the 2PA spectrum of a well-characterized semiconductor, ZnSe. (C) 2004 Optical Society of America.
