Laser-induced formation of elongated modified areas within porous glass impregnated with silver salts

A method of recording modified regions of an extended shape and complex structure, which can act as waveguide microstructures in the bulk of porous glass plates impregnated with solutions of silver salts, under the action of continuous radiation of an ytterbium fiber laser with a wavelength of 1.07 ?m, is considered. The results of studies of modified regions of an extended shape by optical methods are presented. Such microstructures in the volume of glass may well become the basic elements of fiber-optic systems for various purposes.
