Abstract ： Four Nd : CeF3 crystals doped with 0.1, 0.5, 1.0 and 2.0 wt.% Nd3+ are grown, their absorption and fluorescence spectra are measured. The absorption bands of Nd : CeF3 are much wider than that of Nd: YAG. The absorption peak at 353nm does not depend on Nd3+ concentration linearly and there exists no concentration quenching effect while Nd3+ concentration is less than 2.0wt.%. The fluorescence lifetime and the effective stimulated cross section are measured, respectively, as Tr = 300μs and σc = 2.4 x 10-20 cm2 .
