Abstract  Observation of the 532 nm-laser-induced fluorescence spectra of two kinds of Cr:Mg2SiO4 crystalline samples grown in different atomsphere are reported. The experiments were con-ducted at both room temperature and liquid-nitrogen temperature. The fluorescence spectra of the two kinds of samples were different with respect to the polarizing direction of the inducing leser, and two emission bands with different polarized characters and various en-hancement in intensity at low temperatures were also found. In the light of the calculated results by Ms-X$\alpha$ method, the main experimental results are explained.
