Neodymia-doped glasses are currently commercially available for use in laser systems. Typically, these glasses are low-softening-temperature borates, phosphates, silicates, and fluorides. With its high softening temperature, high thermal shock resistance, and low nonlinear index of refraction, silica may be an ideal candidate for a neodymia host glass for high-power laser applications. Conventional glass processing methods, however, have thus far succeeded in incorporating only low levels of neodymia in silica. In this paper, the fabrication of neodymia-silica glasses with high neodymia content by the sol-gel route is described. A possible structure for neodymia in silica is discussed.
