Precipitation of Silver Nanoparticles in Glasses by Laser Irradiation

Nanosecond lasers have been generally utilized in the interior adjustment of transparent materials and precipitation of nanoparticles in glasses with the expanding improvement of laser technology. It is a powerful apparatus for spatially chosen structural adjustments, crystallization, phase change and dissolution in transparent materials. It was illustrated that the function crystals could be precipitated on the surface of glasses by various kinds of continuous wave lasers. Besides, the controlled orientation of some crystals in glass can be accomplished by heat-assisted continuous wave Nd:YAG laser irradiation. An assortment of photonic devices such as; waveguides, couplers , and gratings have been created inside the glasses with two dimensional or three-dimensional designs.
