We have investigated the formation of nanostructure at the surface of 50Bi2O3.50B2O3 glass using XeCl pulsed laser irradiation with a heated support. The growth of a protuberant nanostructure was enhanced by either increasing the support temperature or the laser pulse repetition rate. It was found that the surface protuberances were amorphous with the same composition as the original glass. In order to discuss the relation between the temperature and the structural change, tile Urbach rule was applied to analyse the optical absorption. As a result, we found that the effect of temperature was insufficient for crystallisation in the 50Bi 2O3.50B2O3 glass. Considering the characteristics of the glass, it appears that dynamic randomness is independent of the morphology and only affects the phase change.
