  • NaCl:OH color center laser
    Patent number: 4990322
    Abstract: A powerful and stable color center laser is provided by additively colored NaCl:OH.sup.- crystals. The OH.sup.- impurity is the key dopant for creating color center lasing in NaCl, providing an output tunable over the 1.41 to 1.81 .mu.m region. In addition, modelocked pulses of 5 psec duration are available in a synchronously pumped arrangement, tunable from 1.47 to 1.73 .mu.m.
    Type: Grant
    Filed: July 19, 1990
    Date of Patent: February 5, 1991
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Clifford R. Pollock, Joseph F. Pinto, Efstratios Georgiou
