One-and two-photon absorption of N2-laser radiation (λ = 337 nm) in multicomponent silicate and phosphate glasses is investigated. A monotonic decrease from pulse to pulse in the intensity of radiation passing through a sample and in the luminescence excited by this radiation is found. The possibility of calculating the imaginary part of the cubic nonlinear susceptibility of glasses using the time dependence of the change in the laser intensity at the sample output is shown.
