摘要:

从二氧化硅和元素α-镓之间的界面反射的探测波的强度和相位的同时测量揭示其非常强的光学非线性,影响这两个参数的反射波。该数据证实了光学响应的非热机制,该机制假设在二氧化硅和大块α-镓之间出现仅几纳米厚的均匀的高度金属层。

英文摘要:

Simultaneous measurements of the intensity and phase of a probe wave reflected from an interface between silica and elemental alpha-gallium reveal its very strong optical nonlinearity, affecting both these parameters of the reflected wave. The data corroborate with a non-thermal 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.
