Ultrafast optically induced reflectivity switching at a gallium-silica interface

Ultrafast optically induced reflectivity switching at a gallium-silica interface
Ultrafast optically induced reflectivity switching at a gallium-silica interface
It was reported recently that the reflectivity of a gallium-silica interface held close to, but below, the gallium melting point of 29.8 C can be changed significantly (>40%) by light over a very broad spectral range 400 - 1600 nm. The effect has been attributed to a surface-assisted phase transition from the stable α-gallium phase to a phase of metallic nature. In this paper we present the results on the ultrafast switching dynamics of a gallium-silica interface.

Abstract

It was reported recently that the reflectivity of a gallium-silica interface held close to, but below, the gallium melting point of 29.8 C can be changed significantly (>40%) by light over a very broad spectral range 400 - 1600 nm. The effect has been attributed to a surface-assisted phase transition from the stable α-gallium phase to a phase of metallic nature. In this paper we present the results on the ultrafast switching dynamics of a gallium-silica interface.
