Abstract
Two-photon absorption coefficients in ultraviolet-grade optical fibers are measured in the range of 219-260 nm. A frequency-doubled tunable dye laser is used as the light source. The two-photon absorption coefficient increases exponentially with an increase in the photon energy. The exciton peak does not appear in the spectrum. Theoretical values are calculated by the Keldysh formula and compared with the experimental results.
