title: Measurement of optical homogeneous linewidths in a glass with picosecond accumulated photon echoes.
abstract: Picosecond accumulated photon echoes have been used to study optical dephasing in the (4)I(9/2)?(2)G(7/2), (4)G(5/2) transition of Nd(3+) in silicate glass. The homogeneous width exhibited a T(2.2)temperature dependence similar to that of other rare-earth systems previously studied by fluorescence line narrowing. The wavelength dependence of the echo-decay curves shows that relaxation among crystal-field states takes place in a few picoseconds.
