Abstract: A display device for displaying at least one image includes a receiver device configured to receive image data assigned to the at least one image, an electronic visual display having a plurality of pixels, configured to display the at least one image by emitting light from the plurality of pixels, a control device configured to control the electronic visual display based on the image data to emit light in a first angular range in order to display a first image on the electronic visual display, the first image being registrable in a first observation angular range with respect to the electronic visual display that corresponds to the first angular range.

Abstract: The invention relates to an apparatus (1) for producing short synchronous radiation pulses at different wavelengths, particularly to an optically parametric oscillator, comprising at least one pump radiation source (2), preferably a pump laser, for outputting radiation at a pump wavelength, and a resonator (3) having a wavelength-dependent effective resonator length, wherein the resonator (3) has a non-linear wavelength converter (4) for producing radiation at a first and a second wavelength; a dispersive element (5) having a strong wavelength-dependent delay characteristic; and a coupling-out element (6) for at least partially coupling-out the radiation from the resonator (3). In addition, the invention relates to a method for producing short radiation pulses by means of an apparatus (1), particularly an optically parametric oscillator.
