A method of processing a glass material includes guiding and/or focusing light from a light source to glass material in a hot stage of a processing system, where the light source provides light at a wavelength that interacts with crystals that may be formed in the glass material. The method includes collecting and/or guiding light directed from the glass material in the hot stage to a wavelength separator, and separating the light directed from the glass material to provide a spectrum having wavelengths that are within about twenty nanometers of the wavelength . The method includes observing with a detector light of the spectrum to identify nano-scale shifts in the wavelength caused by interaction with crystals, if present, within the glass material in the hot stage of the processing system.

A method for forming a via in a glass article includes forming one or more cavities within a glass substrate by exposing the glass substrate to an etchant, the glass substrate including a glass cladding layer and a glass central core layer, where the glass cladding layer has an etch rate in the etchant that is different than an etch rate of the glass central core layer, and where the one or more cavities extend through the glass central core layer terminating at the glass cladding layer, depositing a metallic material within the one or more cavities, and removing the glass cladding layer.

A method of forming a coating that includes depositing a multicomponent glass layer on a polymer substrate and depositing a heat absorbing layer on the multicomponent glass layer. Inducing spinodal decomposition of the multicomponent glass layer by annealing the heat absorbing layer, and etching at least one of a phase separated component of the multicomponent glass layer. The spinodal decomposition may be achieved through a pulse thermal or electromagnetic assisted annealing process. The coating may then be used as a hydrophilic surface, or may be fluorinated using conventional methods to produce the superhydrophobic coating.

The invention relates to a process for obtaining a material comprising a substrate coated on at least one part of at least one of its faces with at least one functional layer, said process comprising: a step of depositing the or each functional layer, then a step of depositing a sacrificial layer on said at least one functional layer, then a step of heat treatment by means of radiation chosen from laser radiation or radiation from at least one flash lamp, said radiation having at least one treatment wavelength between 200 and 2500 nm, said sacrificial layer being in contact with the air during this heat treatment step, then a step of removing the sacrificial layer using a solvent,

said sacrificial layer being a monolayer and being such that, before heat treatment, it absorbs at least one part of said radiation at said at least one treatment wavelength and that, after heat treatment, it is capable of being removed by dissolution and/or dispersion in said solvent.
