ABSTRACT A laser calorimeter has been used to measure two‐photon absorption in solids. This new technique provides greater sensitivity than is possible in nonlinear transmission measurements. The two‐photon absorption coefficients of CdTe and CdSe at 1.06 μm using ∼16‐nsec (FWHM) pulses are 0.13±0.04 and 0.050±0.014 cm/MW, respectively.

  • Article: Two-photon absorption: an overview of measurements and principles
    [show abstract] [hide abstract]
    ABSTRACT: The range of organic compounds whose degenerate two-photon absorption (2PA) spectrum has been reported has increased rapidly in recent years, in parallel with the growing interest in applications based on the 2PA process. The comparison of results from different techniques is not always straightforward, and experimental conditions employed may vary significantly. We overview the concepts underlying 2PA measurements and the common assumptions and approximations used in the data analysis for various techniques. The importance of selecting appropriate excitation regimes under which measurements should be performed and of avoiding contributions from absorption mechanisms in addition to 2PA will be emphasized.
