Abstract
We report the dynamical behavior of -sized phase separation for a homogeneous mixture of and 3-methylpyridine (3MP) induced under continuous photon-flux by a focused YAG laser. At a water-rich composition, stable rhythmic oscillation of the emergence-growth escape of a 3MP-rich droplet is generated. In contrast, at a near-critical composition, an emergent droplet exhibits significant nonequilibrium fluctuation. Such dynamic phenomena are interpreted in terms of the effect of a local dielectric field and a dissipative system generated by a focused laser on the binary mixture.
