We investigated the intensity-dependent loss properties of nonlinear crystals by using subpicosecond laser pulses at 264 and 211 nm. Two-photon absorption coefficients for potassium dihydrogen phosphate, β-barium borate, and lithium triborate crystals were obtained from the intensity-dependent transmission measurements.
