A model of multiple shot bulk damage under conditions of multiphoton excitation of glass matrix has been considered. It has been based on the nonsteady thermal self-focusing due to accumulation of color centers and increasing of absorption coefficient of medium at the wavelength of incident radiation. These representations have allowed to explain not only the shape of accumulation curves but the influence of spot size and color centers generation efficiency on the thresholds of single and multiple shot damage, and the influence of variable-valence impurity ions on the processes characteristics too.
