  • Laser with switchable emission wavelength
    Patent number: 4757507
    Abstract: For operating a laser at different wavelengths, at least one of the two mirrors of the oscillator is subdivided into two or more regions with different spectral reflectivity, where each region reflects only one of the emission wavelengths of the laser medium and is largely permeable for the remaining emission wavelengths. Each such region can be inserted separately into the ray path of the laser.
