We report on two photon absorption measurements at 213nm of deep UV transmissible media including LiF, MgF2, CaF2, BaF2, Sapphire (Al2O3) and high purity grades of fused-silica (SiO2). A high stability 24ps Nd:YAG laser operating at the 5th harmonic (213nm) was used to generate a high intensity, long Rayleigh length Gaussian focus inside the samples. The measurements of the Fluoride crystals and Sapphire indicate two photon absorption coefficients between 0.004 and 0.82 cm/GW. We find that different grades of fused silica performed near identically for two photon absorption, however, there are differences in linear losses associated with purity. A low two photon absorption cross section is measured for MgF2 making it an ideal material for the propagation of high intensity deep UV lasers.
