A method is proposed for producing a packaging, having a method step of microperforation of a flexible material as a packaging film, comprising: provision of the flexible material as a packaging film, transport of the flexible material over a transport section, provision of a laser in order to generate a perforation of the flexible material with its beam. For a packaging with improved gas exchange, a laser system with a wavelength in the range of from 150 nm to 1064 nm, preferably from 355 nm to 532 nm, is used for the laser, and the perforation with the laser is carried out during the movement of the flexible material of the packaging film during the transport.

Methods, systems, devices, and substrates are described. In some examples, an apparatus may include optical components configured to adjust an input to a laser cutting optic for modifying a substrate (e.g., an optically transmissive substrate). In some examples, the optical components may include a beam deflector, a first optic configured to output a first laser beam with a first beam width, and a second optic configured to output a second laser beam with a second beam width. In some examples, the beam deflector may modify an optical path of a pulsed laser (e.g., through the first optic or through the second optic), which may result in an input to the laser cutting optic having a beam width corresponding to the first optic or the second optic. The different input beam widths may modify a line focus intensity of an output of the laser cutting optic when modifying the substrate.

A substrate manufacturing method of manufacturing a substrate from a workpiece is disclosed. A laser beam is first split and condensed to form a plurality of focal points aligned side by side along a first direction, and with the focal points positioned inside the workpiece, the focal points and the workpiece are moved relative to each other along a second direction orthogonal to the first direction such that a separation layer is formed. A region of the focal points and the workpiece are then moved relative to each other along the first direction. These relative movements are alternately and repeatedly performed. The splitting and condensation of the laser beam are performed such that a volume expansion of the workpiece associated with the formation of the modified regions is relatively small in the vicinity of at least one focal point formed on a center side.

The controller controls the spatial light modulator so that a converging point of the 0th-order light in the Z direction is located on an opposite side of a converging point of non-modulated light of the laser light with respect to an ideal converging point of the 0th-order light.
