Abstract
Transmission of fused silica, CaF2, LiF, and MgF2 is measured using 450-fsec, 248-nm pulses in the range 10–120 GW/cm2. Different loss mechanisms such as scattering of transmitted radiation, color-center formation, and multiphoton absorption were studied separately. For fused silica a two-photon absorption mechanism is found, while for CaF2, LiF, and MgF2 three-photon absorption and absorption due to color-center formation are found as dominant absorption mechanisms.
