An experimental investigation was made of the dependence of the transmission of BaF{sub 2} and Al{sub 2}O{sub 3} samples on the intensity of KrF-laser radiation ({lambda} = 248 nm) pulses of 85 ns duration. The two-photon absorption coefficients were found at {lambda} = 248 nm and their values for these two crystals were 0.5 {+-} 0.2 and 2 {+-} 1 cm Gw{sup -1}. The surface and bulk laser breakdown thresholds were determined for these samples. (nonlinear optical phenomena)
