“…In 1997, Zellmer et al [148] demonstrated a 100 mW all fiber laser system in which a Tm 3+ /Yb 3+ -doped ZBLAN fiber was pumped with a 2.8 W diode pumped Nd 3+ -doped silica fiber laser at 1065 nm. In the same year, Paschotta et al [129] achieved the highest output (230 mW) of 480 nm light from a Tm 3+ -doped ZBLAN fiber laser pumped by a 1.6 W Nd:YAG laser at 1123 nm. However, the fiber laser performance degraded quickly at high-power operation.…”

-NaF), considered as the most stable heavy metal fluoride glass and the excellent host for rare-earth ions, has been extensively used for efficient and compact ultraviolet, visible, and infrared fiber lasers due to its low intrinsic loss, wide transparency window, and small phonon energy. In this paper, the historical progress and the properties of fluoride glasses and the fabrication of ZBLAN fibers are briefly described. Advances of infrared, upconversion, and supercontinuum ZBLAN fiber lasers are addressed in detail. Finally, constraints on the power scaling of ZBLAN fiber lasers are analyzed and discussed. ZBLAN fiber lasers are showing promise of generating high-power emissions covering from ultraviolet to mid-infrared considering the recent advances in newly designed optical fibers, beam-shaped high-power pump diodes, beam combining techniques, and heatdissipating technology.

“…Incorporating the fluoride host in an optical waveguide geometry can also offer low thresholds and high efficiencies, increasing the potential for continuous wave (CW) operation at room temperature and at relatively high power levels. This has been demonstrated most effectively with ZBLAN optical fibers [3]- [5].…”

Abstract-We report the first fabrication and laser operation of channel waveguides based on LaF 3 planar thin films grown by molecular beam epitaxy. To our knowledge, this is the lowest phonon energy dielectric material to have shown guided-wave laser operation to date. A full characterization, in terms of spectroscopy, laser results, and propagation losses, is given for the planar thin films upon which the channel waveguides are based. Two channel-fabrication methods are then described, the first involves ion milling and the second takes the novel approach of using a photo-definable polymer overlay. Laser operation in Nd-doped samples is demonstrated at 1.06, 1.05, and 1.3 m, and the potential for mid-infrared laser sources based on such guides is discussed.

“…In that sense, lanthanide ions are among the most studied dopants and particularly Tm 3+ is notable due to the wide range of fields in which its emissions are potentially applicable. This is partly thanks to the energetic position of its infrared emissions, interesting in optical communications, surgery or remote sensing, and partly thanks to the resonant character of many transitions that allow efficient up-conversion processes that generates visible frequencies [7][8][9][10].…”

Abstract:In this work micro-Raman scattering experiments have been performed in LiNbO 3 :Tm 3+ samples with waveguides fabricated by Zn 2+ indiffusion. The results shown that Zn 2+ ions enter the lattice in Li + sites, but also in interstitial positions. This produces a compaction of the lattice close to the surface of the sample, generating the waveguide. It is shown that this region is surrounded by a different area in which the lattice is relaxed to recover the characteristic lattice parameters of LiNbO 3 :Tm 2108-2114 (2007). 11. R. Nevado, and G.
