Intensity-dependent transmission properties of window materials at 193-nm irradiation.
We measured the transmission of MgF(2), CaF(2), BaF(2), and fused-silica window materials, using 0.8-ps optical pulses at 193 nm with intensities from 1 to 300 GW/cm(2). The two-photon absorption coefficients beta are extracted from these measurements. The excited excitonic fluorescence in CaF(2) and BaF(2) shows a quadratic dependence on the irradiation intensity in a wide range.
