Abstract: A computing system receives a request to create a digital data object from a user device of a user. The request includes user data for the digital data object. The computing system generates the digital data object based on one or more parameters of the user data. The computing system generates a quick response (QR) code associated with the digital data object. The QR code uniquely identifies the digital data object. The computing system causes a physical copy of the digital data object to be printed by causing display of the QR code on an output device, and causing scanning of the QR code. The scanning of the QR code causes a printer to print the physical copy of the digital data object.

Abstract: A laser system includes a laser radiation source for providing pulsed laser radiation, and an optical system that includes a first polarization setting optical unit configured to set a circular polarization state of the pulsed laser radiation and a multipass cell having at least two mirrors. The pulsed laser radiation passes through the multipass cell with formation of a plurality of intermediate focus zones. The multipass cell is filled with a filling gas that has an optical nonlinearity and causes a spectral broadening of the pulsed laser radiation in the intermediate focus zones. A pressure of the filling gas is set in a pressure range so that there is an ionization behavior of the filling gas in a form of multiphoton ionization. Focus diameters of the intermediate focus zones are set such that the pulsed laser radiation passes through the multipass cell without ionization of the filling gas.

The pulsed laser radiation passes the multipass cell with formation of a plurality of intermediate focus zones. The multipass cell is filled with a gas having an optical nonlinearity that causes an intensity-dependent rotation of an alignment of the elliptical polarization state of the pulsed laser radiation, such that the multipass cell outputs beam portions having differently aligned elliptical polarization states on account of the intensity-dependent rotation. The optical system further includes an optical beam splitting system for splitting the beam portions having differently aligned elliptical polarization states.
