A very recently developed high T-m (melting temperature) optical glass
doped with C-60/C-70 molecules has been studied. Using a picosecond l
aser operating at 532 nm, the observed time-resolved degenerate-four-w
ave-mixing (DFWM) spectra show remarkable changes with addition of ful
lerene into the glass host. (C) 1996 American Institute of Physics.
