Efficient neodymium-doped glass-ceramic fiber laser and amplifier

Abstract

We report an efficient glass-ceramic fiber laser and show that its slope efficiency (~30%) is not compromised by the presence of Nd-doped fluoride crystals embedded within the core of the single-mode optical fiber. In contrast, the spectroscopy (fluorescence and gain spectrum) of the Nd(3+) ions is dramatically changed by the ceramming process, an indication of strong partitioning of the rare-earth ions into the CdF(2):PbF(2):YF(3) crystal environment. The enormous potential for a new range of optical devices based on transparent glass-ceramic materials is highlighted.

Erbium emission properties in nanostructured fibers

“…This is usually obtained for dimensions less than several tens of nanometers [11] in the case of dielectric nanoparticles, depending on their composition and on the expected application. In most cases the fiber core glass is a non-silica or a very low silica material made by the double crucible furnace melting procedure [12]. However these materials are not as reliable as compared to silica based rare earth-doped fibres.…”

Glass and Process Development for the Next Generation of Optical Fibers: A Review

“…The continued growth of NCs can increase the light scattering and so the optical loss in the resulting glass/fiber. Alternatively, controlled growth of NCs in the glass during fiber drawing is challenging and, thus, to date, has resulted in relatively high loss fibers [70,71].…”

“…However, the nanoparticle may also be amorphous, such as those obtained by phase separation (Zarzycki, 1991). Some reports on RE-doped transparent glass ceramic based single mode fibers use low melting mixed oxides prepared by a rod-in-tube technique (Samson et al, 2002), or mixed oxyfluorides using a double-crucible technique (Samson et al, 2001). However, the low melting point of these materials causes low compatibility with silica components.…”
