Abstract

An apparatus for producing various laser wavelengths from the same laser medium by means of resonator mirrors. In accordance with the apparatus any desired, given combination of laser wavelengths can be brought to emission simultaneously or at least in very rapid alternation (switching time 1 ms) with the use of standard resonator mirrors linearly arranged outside of a laser medium, with part of at least one of the resonator mirrors being configured so that it serves as resonator limitation for a certain laser wavelength or wavelength group but another part of the at least one of the resonator mirrors constitutes an intracavity element for the respective other wavelength(s) or wavelength group(s).
