  • Frequency doubled ultraviolet laser
    Patent number: 5179562
    Abstract: A frequency doubled ultraviolet laser comprising means for enabling a beam of coherent electromagnetic radiation to be propagated along an intracavity path, means for holding and translating an anisotropic crystal in this path, means for detecting the crystal temperature relative to the optimum frequency doubling temperature, and means for correcting any shortfalls in the efficiency of ultraviolet generation by adjusting the crystal temperature, crystal position, and/or the intensity of the fundamental beam.
