Light-induced structural transformations and optical nonlinearity in gallium nano-films and self-assembled nanoparticles
Light-induced structural transformations and optical nonlinearity in gallium nano-films and self-assembled nanoparticles
We report observation of an optical nonlinearity in gallium nano-particles resulting from a light-induced structural transformation in the metal which is known for its incredible polymorphism. A freshly cleaved single-mode optical fiber was put into a vacuum chamber and cooled to 100 K. The end of the fiber was exposed to a beam of gallium atoms, leading to the steady deposition of a gallium layer, thus forming a mirror made of just a few picograms of material. The gallium forms nano-particles by self-organization. These particles are relatively uniform in size, with a diameter typically between 80 and 200 nm, which depends on the thickness of the gallium film from which they formed.

Abstract
We report observation of an optical nonlinearity in gallium nano-particles resulting from a light-induced structural transformation in the metal which is known for its incredible polymorphism. A freshly cleaved single-mode optical fiber was put into a vacuum chamber and cooled to 100 K. The end of the fiber was exposed to a beam of gallium atoms, leading to the steady deposition of a gallium layer, thus forming a mirror made of just a few picograms of material. The gallium forms nano-particles by self-organization. These particles are relatively uniform in size, with a diameter typically between 80 and 200 nm, which depends on the thickness of the gallium film from which they formed.
