Abstract
Transmission dependencies of optical materials samples BaF2, Al2O3 and CaF2 (the infrared range sample) from KrF-laser radiation intensity with pulse duration of 85 ns are experimentally received. From these dependencies, two-photon absorption coefficients at laser wavelength 248 nm are found which for the appropriate materials are equal to 0.5 +/- 0.2, 2 +/- 1 and 30 cm/GW. Laser damage thresholds of the surface and volume of the investigated samples at 248 nm are also determined.
