Abstract
For long incident pulses, measurement of two-photon absorption coefficients can be complicated by excited-state absorption. We develop here a quantita tive ab initio model to determine the contribution of excited-state absorpt ion in the interpretation of the two-photon absorption data for such materi als. We present representative calculations of this effect for some selecte d systems. (C) 2000 John Wiley & Sons, Inc.
