Lh. Acioli et al., VIOLET-BLUE EMISSIONS DUE TO FREQUENCY UP-CONVERSION IN ND3-DOPED FLUOROINDATE GLASSES(), Journal of luminescence, 72-4, 1997, pp. 68-70
We report the observation of intense frequency up-conversion in Nd3+-d
oped fluoroindate glasses pumped lay the second harmonic of a cw mode-
locked Nd:YAG laser. Mechanisms for generating the observed emissions
are discussed.
