摘要：
Femtosecond pulses at lambda = 264 nm were used to measure the two-photon absorption (TPA) coefficient in beta -BaB2O4 (BBO) crystal. It was found that nonlinear absorption in BBO depends significantly on crystal cut and/or beam polarization. For an ordinary beam propagating along the optical axis (\ \c) and perpendicular to it (perpendicular toc) the similar values of TPA coefficient were obtained, namely (68 +/- 6) x 10(-11) and (66 +/- 7) x 10(-11) cm/W. For an extraordinary beam (perpendicular toc) the TPA coefficient is significantly smaller, (47 +/- 5) x 10(-11) cm/W. (C) 2001 Elsevier Science B.V. All rights reserved.
