概要	A novel method for uniform dispersion of the rare earth ions in SiO2 glass is presented. Nd doped SiO2 laser glass has been made by aluminum co-doping to avoid quenching due to Nd clustering. Previous works with aluminum co-doping were passive methods because uniform dispersion of the rare earth ions in SiO2 glass depended only on aluminum co-doping effect. Concentration quenching of Nd laser glass is explained by cross-relaxation process and depends on Nd-Nd distance in the glass. The shorter the Nd-Nd distance the stronger is quenching, so the distance should be greater than some minimum. Homogeneous rare earth doped SiO2 glass is achieved by a modified sol-gel method using zeolite X...
