A transparent mixed alkali tellurite glass of 10Li2O-10Na2O-80TeO2 containing LiNbO3 crystals with a diameter of about 4μm and with the amount of about 6 mass% is prepared using an incorporation method, and LiNbO3-doped tellurite glass fibers are drawn. LiNbO3 particles in the fiber and bulk samples are well dispersed. The samples also have a good transparency. The mixed alkali tellurite glass with a high thermal stability against crystallization and with a high refractive index of n=1.98 is very suitable for incorporation of LiNbO3 crystals and for LiNbO3-doped fiber drawing. This technique will be applicable for fabrications of nonlinear optical glass fibers containing various nonlinear optical crystals.
