A laser processing system that can effectively blow out a material of a workpiece melted by a laser beam by effectively utilizing an assist gas emitted from a nozzle. The laser processing system comprising a nozzle including an emission opening configured to emit a jet of an assist gas along an optical axis of a laser beam, the nozzle being configured to form a maximum point of velocity of the jet at a position away from the emission opening; a measuring instrument configured to measure a sound generated by the jet impinging on an object; and a position acquisition section configured to acquire information representing the position of the maximum point based on output data of the measuring instrument.

An additive manufacturing apparatus manufactures a shaped object by stacking layers in each of which unit beads that are solidified products of a molten material are laid side by side. The additive manufacturing apparatus includes a material supply unit that supplies a wire as the material to a workpiece, an irradiation unit that emits a laser beam for melting the material supplied, and a controller device that controls the material supply unit and the irradiation unit to form the unit beads. In the formation of unit beads brought into contact with each other to form the layer, the controller device performs control such that a formed unit bead is flattened by irradiation with the beam, and a unit bead is formed in contact with the unit bead that has been flattened.

A curable resin or adhesive composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and at least one energy converting material, preferably a phosphor, capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

The disclosure relates to methods and systems incorporating physical modeling to identify the ultrafast laser/material interaction mechanisms and the impact of laser parameters, to optimize implementation of ultrafast laser-based processing for a given material. The process determines a laser fluence near the ablation threshold for a given material and given pulse duration. The repetition rate, scanning speed and scanning strategy are subsequently optimized to minimize heat accumulation, having an operable line scan overlap between 50% to 85% for achieving smooth ultrafast-laser polishing, while maintaining an optic-quality surface.
