We present a nonlinear optical (NLO) probe technique, wavelength-dependent Z-scan nonlinear spectroscopy (WDZNS), which can be utilized for assessing broadband NLO properties of materials. Unlike typical Z-scans, WDZNS can spectrally monitor the frequency-doubled output as a function of wavelength lambda as well as input intensity I. Based on WDZNS we have investigated the strong impact of two-photon absorption (TPA) on second-harmonic generation in CdTe over a broad TPA range. This complicated NLO effect is characterized by the lambda-dependent TPA coefficient, which is consistent with a simple two-band model. The relative second-order NLO dispersion derived from WDZNS is also consistent with previous measurements. (C) 2013 Optical Society of America
