Quantum efficiency for F-center production by two-photon absorption
Abstract
Color centers are produced in KBr and KI by two-photon absorption from a frequency-doubled ruby laser beam. An empirical formula is obtained for the dependence of the quantum efficiency for F-center formation on the concentration of F-centers produced. Measured values for the two-photon absorption coefficient are also reported.
