Abstract
The glass-crystalline transformation induced by laser irradiation is s tudied in MoO3. Before crystallization we have found that the system e volves from a low temperature glass phase to a high temperature glass phase. The crystallization kinetics depend strongly on the initial irr adiation power. The power densities needed to induce the phase transfo rmations, of the order of 15 W/mm(2), are relatively low and suggest t he possibility of using this material as a data storage medium.
