Abstract :
Summary form only given, as follows. The authors show that structural and phase transformation in the V/sub 2/O/sub 5/-VO/sub 2/ system is connected with processes stimulated by laser radiation in the volume of the crystal V/sub 2/O/sub 5/. In the structure of the vanadium pentoxide there are channels in the direction [001] and [010] with effective diameter of 2 Å. Along these channels oxygen diffusion to the crystal surface takes place stimulated by the laser radiation.
