A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Users may collaborate while designing the apparel and designate what items should belong in specific collections. Users may also use an assortment builder tool to search a database of products according to one or more search parameters to select a garment with a finishing pattern.

A method for hardening a transparent material includes the steps of introducing a material modification to the transparent material using a laser beam of ultrashort laser pulses of an ultrashort pulse laser so as to harden at least a portion of the transparent material.

Disclosed is a way of providing a surface processing method for concrete in which vitrifying is suppressed even when high-speed processing is performed. In a surface processing method of concrete, a surface of the concrete is irradiated with a laser beam so that a beam spot is scanned along a predetermined scanning pattern and the scanning pattern moves along the surface at a predetermined feed speed. When the beam spot repeatedly passes through a predetermined portion in the scanning pattern, an overlap ratio, which is a ratio of overlapping of a passage path of the beam spot over a passage path of the beam spot in an immediately preceding irradiation, is 90% or less.

A method of selectively removing at least part of a first phase from a surface of a nanocomposite includes at least a first phase and a second phase, each phase having a respective threshold fluence under a given number of applied laser pulses for removal of the phase by laser ablation. The threshold fluence of the first phase is less than the threshold fluence of the second phase. The method includes irradiating the surface of the nanocomposite with a laser beam having a laser beam diameter, a laser pulse duration, and a laser pulse energy during the irradiation. The laser fluence during the irradiation is less than the threshold fluence of the second phase and greater than the threshold fluence of the first phase. The laser beam diameter is greater than an average grain size of the first phase at the surface of the nanocomposite.

The present disclosure provides methods and systems for composite-to-metal hybrid bonded structures compromising the laser surface treatment on titanium alloys to promote adhesive bond performance. For example, a computer may be programmed to set a laser path corresponding to a predetermined geometric pattern. A laser may be coupled to the computer and apply a pulsed laser beam to a contact surface of the titanium alloy along the predefined geometric pattern. The laser may generate an open pore oxide layer on the contact surface of the substrate with a thickness of 100 and 500 nm. The open pore oxide layer may have a topography corresponding to the predefined geometric pattern. The topography may contain high degree of open pore structure and promote adhesive bond performance. Adhesive, primer or composite resin matrix may fully infiltrate into the open pore structures. Adhesive and composite laminate may co-cure to form composite-to-titanium hybrid bonded structures.
