Abstract
Simultaneous measurements of the intensity and phase of a probe wave reflec ted from an interface between silica and elemental alpha -gallium reveal it s very strong optical nonlinearity, affecting both these parameters of the reflected wave. The data corroborate with a nonthermal mechanism of optical response which assumes appearance of a homogeneous highly metallic layer, only a few nanometer thick, between the silica and bulk alpha -gallium.
