Abstract: A method for producing a recess or through-opening in a substrate includes applying pulsed laser radiation to the substrate. The laser radiation is focused using an optical system at an original focal depth and, by non-linear self-focusing within the pulse duration of an individual pulse, is also focused by the optical system at a focal depth different from the original focal depth. A difference between the focal depths corresponds to or is greater than the longitudinal extent of the recess or though-opening to be produced. The laser radiation modifies the substrate along a beam axis of the laser radiation in the region of the recess or through-opening, but does not result in removal of the substrate material necessary to form the recess or the through-opening. The substrate material in the modified region is anisotropically removed to produce the recess or through-opening in the substrate.

Abstract: A process is described for laser welding a sheet metal workpiece having an anti-corrosion pre-coat on at least one major surface thereof and having first and second opposite side edges. The sheet metal workpiece is arranged such that the first and second side edges are in contact with one another and such that the at least one major surface faces outwardly. A laser beam having a first beam spot-size, is used to form a laser weld joint between the first and second side edges. Subsequently, a localized anti-corrosion surface layer is formed on the laser weld joint. To this end, a laser beam having a second beam spot-size larger than the first beam spot-size is scanned along the laser weld joint. During the scanning, a flow of a powdered anti-corrosion surface layer material is directed toward a portion of the laser weld joint that is being irradiated by the laser beam. The laser beam melts the material, which subsequently solidifies to form a layer adhering to the laser weld joint.

The systems, devices, and methods may be used to heat a sample holder, the sample holder configured to receive a sample container holding the frozen sample. A sample thaw start time may be identified by measuring a temperature of the sample container and/or a temperature of the sample. A sample thaw end time may be calculated as a function of the sample thaw start time.
