Abstract

Abstract

We investigated the nonlinear optical properties of single- and poly-crystalline optical materials using ultrashort mid-infrared laser pulses between 3 and 4 µm. We compared visible to mid-infrared spectra between the materials. Measured energy conversion into all-order harmonics in polycrystalline materials exceeded 30%.

Abstract

Abstract

We investigate the nonlinear optical properties of a series of two-photon absorbing chromophores in the femtosecond regime using both two-photon induced fluorescence spectroscopy and the Z-scan technique. We apply a simplified sum-over-states model to the experimental data to predict nonlinear refraction.
