In a process and an apparatus for generating at least three light bundles of different wavelength for displaying color images, one of these light bundles having a longest wavelength and another of the light bundles having a shortest wavelength, which light bundles are obtained by an OPO and further nonlinear optical component elements from a signal beam and/or idler beam of the OPO and/or a primary light bundle, from which a beam exciting the OPO is also derived, it is provided that at least a partial light bundle is separated from the primary light bundle for exciting the OPO, in that the light bundle with the longest wavelength and the light bundle with the shortest wavelength are obtained from the signal beam and/or idler beam of the OPO by way of frequency multiplication and/or frequency mixing with another partial light bundle of the primary light bundle by excluding components of light bundles other than the generated light bundles with the shortest and longest wavelengths for image display. |
