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 coeff icient increases exponentially with an increase in the photon energy. The exciton peak does not appear in the spectrum. Theoretical values a re calculated by the Keldysh formula and compared with the experimenta l results.
