    "abstract": "Simultaneous measurements of the intensity and phase of a probe wave\nreflected from an interface between silica and elemental alpha-gallium reveal\nits very strong optical nonlinearity, affecting both these parameters of the\nreflected wave. The data corroborate with a non-thermal mechanism of optical\nresponse which assumes appearance of a homogeneous highly metallic layer, only\na few nanometer thick, between the silica and bulk alpha-gallium.",
