  • Patent number: 11668961
    Abstract: A phase and phase/amplitude spatial light modulator arrangement for generating a complex-valued light field with a spatial light modulator, a phase element and an optical system. The phase and amplitude spatial light modulator arrangement is configured to generate a light field that is adjustable in amount and phase. A method realizes operation of a combined spatial light modulator for generating a complex-valued light field. Here, the method includes adapting an optical characteristic in several areas of a phase element. A further method realizes operation of an optical arrangement for modulating different light wavelengths by adjusting several wave influences in several areas of a phase modulator. A last method realizes operation of an optical arrangement by adjusting an amplitude spatial light modulator for modulating light intensities in at least two optical paths.

  • Publication number: 20080028792
    Abstract: A method for manufacturing an optical component in which an optical function of the component is created for electromagnetic radiation in an application wavelength range, using laser machining with laser radiation in a machining wavelength range, characterized in that the following steps are carried out: 1) A solid body is provided that is made from a material that in the raw state absorbs the laser radiation in the machining wavelength range, 2) Laser machining is carried out on the solid body employing one or more machining steps and 3) The material of the solid body is transformed into a final state in which the solid body is transparent to the electromagnetic radiation in the application wavelength range and thus fulfills the intended optical function.
