Photoreduction of samarium-doped ${\mathrm{BaCl}}_2$ -modified aluminofluoride glass by femtosecond laser irradiation and x-ray irradiation were investigated. Photoluminescence of samarium ions indicated that photoreduction of ${\mathrm{Sm}}^{3+}\to {\mathrm{Sm}}^{2+}$ efficiently occurred in glass samples containing more than $5\mathrm{mol}\mathrm{.}\%$ ${\mathrm{BaCl}}_2$ after femtosecond laser irradiation, while dramatic change was not observed by x-ray irradiation. Transmission electron microscope results revealed that ${\mathrm{BaCl}}_2$ nanophases only precipitated from glass matrix with a high ${\mathrm{BaCl}}_2$ content by focusing femtosecond laser irradiation. Samarium ions were selectively incorporated into the precipitated nanophases, resulting in the enhancement of ${\mathrm{Sm}}^{3+}$ photoreduction under lower laser power.
