Scattering loss in Nd-doped silica based optical fibers

Thermo-optical properties and nonradiative quantum efficiency of Er3+-doped and Er3+/Tm3+-co-doped tellurite glasses

“…For example, spectroscopic studies of co-doped samples have been reported for Er 3+ /Eu 3+ -co-doped tellurite fibers at 800 nm [4], for Er 3+ /Tm 3+ -co-doped tellurite glasses at 650 nm [5] and for Nd 3+ in silica gel films containing silicon quantum dots at 587 nm [9]. The motivations that drive these studies are the strong interest in understanding the fundamental aspects of these types of materials, as well as the exploration of potential applications in a variety of fields, such as optical communication systems, sensor devices, therapeutic applications and development of new solid-state short-wavelength lasers [4,5,12]. This being the case, the characterization of the nonlinear optical and thermal-optical properties of the glasses is very important for optimization of the application of these materials.…”
