Abstract
(EN)

The invention relates to a method (100) for treating an optical spacer (203) for a Fabry-Perot resonator (205) comprising the steps of:

    • arranging the optical spacer in a Fabry-Perot resonator;
    • arranging the Fabry-Perot resonator in an optical system (200);
    • aligning a spatially modulated treatment beam (232) with the Fabry-Perot resonator, wherein the light is short-wave and thereby suitable to cause a change in the refractive index of the optical spacer;
    • aligning a test beam (212) with the Fabry-Perot resonator;
    • spatially resolved detecting of a reflected or transmitted portion of the test beam aligned with the Fabry-Perot resonator, wherein the reflected or transmitted portion indicates location-dependent resonance wavelengths of the Fabry-Perot resonator;
    • spatially resolved adjusting of a location-dependent irradiance of the spatially modulated treatment beam based on the detected reflected or transmitted portion.
