Abstract

We report on a study of the dynamics of a recently discovered light-induced, surface-assisted, structural phase transition from a common orthorhombic phase of α-gallium to a highly reflective phase that occurs at temperatures just below the metal's bulk melting point (30°C). It is fully reversible with dynamics occurring on a nanosecond/microsecond time scale and can be stimulated by very low-intensity radiation, typically approx. 10^-5 W/μm². The two gallium phases involved have significantly different optical properties and this difference gives rise to a gigantic optical nonlinearity, χ⁽³⁾ approx. 1 esu, that offers tremendous new opportunities for controlling light with light. The microscopic model of the effect is discussed.
