Abstract
The thermodiffusive effect induced by a c.w. laser beam in a micellar phase located near a diphasic domain results in a phase separation. Th e micrometric droplets of the new phase nucleated in the initial one a re trapped on the beam axis by electrostrictive effect and self-focuse the laser beam. This self-focusing is characterized by an hysteresis similar to that of the ferromagnetic material magnetization.
