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.
