Abstract

Abstract Translated from German Zum Betrieb eines Lasers in verschiedenen Wellenlängen ist mindestens einer der beiden Spiegel des Oszillators in zwei oder mehrer Bereiche (3.1, 3.2) mit unter­schiedlichem spektralen Reflexionsvermögen eingeteilt, wobei jeder Bereich nur eine der Emissionswellenlängen des Lasermediums reflektiert und für die übrigen Emis­sionswellenlängen weitgehend durchlässig ist. Jeder derartige Bereich ist getrennt in den Strahlengang (4) des Lasers einschiebbar. To operate a laser in different wavelengths, at least one of the two mirrors of the oscillator is divided into two or more areas (3.1, 3.2) with different spectral reflectivities, each area reflecting only one of the emission wavelengths of the laser medium and being largely transparent to the other emission wavelengths. Each such area can be inserted separately into the beam path (4) of the laser.
