A method of laser drilling a hole comprising providing a laser source at a first side of a component to laser drill a hole through the component. A light source is positioned in the path of the laser beam at the opposite side of the component. A camera is provided at the first side of the component. The camera is positioned such that it has a line of sight view of the light source through the laser drilled hole. The laser drilled hole in the component is viewed using the light provided by the light source at the opposite side of the component. The parameters of the laser drilled hole are measured using the view of the laser drilled hole provided by the camera and a flow of gas is provided over the surface of the light source to protect the light source.

Methods and apparatus for applying internal features or complex mechanical structures to a surface of a metal part are disclosed. According to one aspect of the present invention, a method for creating an assembly that includes a substrate and a molded piece involves obtaining the substrate, and forming at least one binding feature on a surface of the substrate. The method also includes molding on a surface of the binding feature and the surface of the substrate. Molding on the surface of the binding feature and the surface of the substrate mechanically binds the molded piece to the substrate.

The invention relates to a method for laser boring or laser cutting a workpiece (2), wherein—electromagnetic radiation (10) emitted from a laser strikes the workpiece (2) and—a liquid (16) which contains nanoparticles (18) is located on a workpiece (2) face facing away from the laser such that—the electromagnetic radiation (10) emitted by the laser strikes the nanoparticles (18) when the electromagnetic radiation (10) has passed through the workpiece (2). The nanoparticles are designed such that the majority of the electromagnetic radiation (10) is absorbed by the nanoparticles (18) in that the electromagnetic radiation (10) generates collective excitations, in particular plasmons such as surface plasmons for example, in the nanoparticles (18).

Systems and methods are provided for adjusting a laser beam applied to a workpiece in a processing operation. A laser processing system receives the laser beam that is associated with a beam quality property. The laser processing system adjusts the laser beam to change the beam quality property based on a characteristic of the workpiece, a characteristic of the processing operation, or a combination thereof. The adjusted laser beam can also be delivered to the workpiece.

A method of fabricating a high-density array of holes in glass is provided, comprising providing a glass piece having a front surface, then irradiating the front surface of the glass piece with a UV laser beam focused to a focal point within +/−100 μm of the front surface of the glass piece most desirably within +/−50 μm of the front surface. The lens focusing the laser has a numerical aperture desirably in the range of from 0.1 to 0.4, more desirably in the range of from 0.1 to 0.15 for glass thickness between 0.3 mm and 0.63 mm, even more desirably in the range of from 0.12 to 0.13, so as to produce open holes extending into the glass piece 100 from the front surface 102 of the glass piece, the holes having an diameter the in range of from 5 to 15 μm, and an aspect ratio of at least 20:1. For thinner glass, in the range of from 0.1-0.3 mm, the numerical aperture is desirably from 0.25 to 0.4, more desirably from 0.25 to 0.3, and the beam is preferably focused to within +/−30 μm of the front surface of the glass. The laser is desirable operated at a repetition rate of about 15 kHz or below. An array of holes thus produced may then be enlarged by etching. The front surface may be polished prior to etching, if desired.
