Porous glass with high-SiO₂ content was impregnated with Nd ions, and subsequently sintered at 1100 °C into a compact non-porous glass in air or reducing atmosphere. Sintering in a reducing atmosphere produced an intense violet–blue fluorescence at 394 nm. However, the sintering atmospheres almost did not affect the fluorescence properties in the infrared range. A good performance Nd³⁺-doped silica microchip laser operating at 1064 nm was demonstrated. The Nd-doped sintering glasses with high-SiO₂ content are potential host materials for high power solid-state lasers and new transparent fluorescence materials.
