“…This suggests that efficient UV emission can be achieved with tandem configurations, that is, using visible upconversion fiber lasers to pump UV upconversion lasers. [147]. Maximum output of 106 mW with a conversion efficiency of 30% was achieved by using two 600 mW laser diodes at 1137 nm.…”

-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.

“…Moreover, an efficient upconversion laser in the visible region pumped by an infrared laser diode has been obtained with a higher efficiency than that achieved by second harmonic generation techniques due to broad pumping mechanisms. [18][19][20] This work presents for the first time, as far as we know, the synthesis of Er 3+ -doped Y 3 Ga 5 O 12 (YGG) nano-garnet using an easy citrate sol-gel method, as well as the study of the correlation between the nanocrystal structure and morphology and the Stokes and upconverted luminescence properties. This characterization was carried out as a function of the concentration of the optically active ion in order to carefully control the Er 3+ luminescence in the nano-garnet.…”

A novel Y 3(1Àx) Er 3x Ga 5 O 12 nanocrystalline garnet has been synthesized by a sol-gel technique and a complete structural, morphological, vibrational, and optical characterization has been carried out in order to correlate the local structure of the Er 3+ ions with their optical properties. The synthesized nanocrystals are found in a single-phase garnet structure with an average grain size of around 60 nm. The good crystalline quality of the garnet structure is confirmed by FTIR and Raman measurements, since the phonon modes of the nano-garnet are similar to those found in the single crystal garnet. Under blue laser excitation, intense green and red visible and 1.5 mm infrared luminescences are observed, whose relative intensities are very sensitive to the Er 3+ concentration. The dynamics of these emissions under pulsed laser excitations are analyzed in the framework of different energy transfer interactions. Intense visible upconverted luminescence can be clearly observed by the naked eye for all synthesized Er 3+ -doped Y 3 Ga 5 O 12 nano-garnets under a cw 790 nm laser excitation. The power dependency and the dynamics of the upconverted luminescence confirm the existence of different two-photon upconversion processes for the green and red emissions that strongly depend on the Er 3+ concentration, showing the potential of these nano-garnets as excellent candidates for developing new optical devices. A IntroductionNowadays, rare earth (RE 3+ )-doped nanocrystals attract great attention due to their size, shape, and phase-dependent structural and luminescence properties, which make them suitable for fundamental and technological applications.1,2 On the other hand, the favorable physical and chemical properties of the oxide garnet crystals, such as high transparency from the UV to the mid-IR, high thermal conductivity, hardness, good chemical stability, and relatively low-energy phonons, make them one of the most important families of host matrices for the RE 3+ ions with interesting luminescence properties already used in lasers and phosphors. ions without charge compensation. 8,9From the point of view of the potential optical applications of the RE 3+ ions, one of the most interesting phenomena is their capacity to convert the infrared absorbed radiation into visible emitting light, known as energy upconversion.10 The particular selection of one or various RE 3+ ions and their concentrations allows controlling the upconverted visible luminescence to match a specific coordinate of colour, or even the generation of white light as a combination of red, green and blue (RGB) emissions. Thus there is an increasing demand for upconversion materials with important applications in upconversion lasers, due to the availability of powerful near-infrared commercial laser diodes, IR detection by conversion to visible light, where detectors are more efficient, and biological fluorescence labels and imaging or 3-D displays. 1,2,[11][12][13][14][15][16] When the RE 3+ ions are incorporated into the nanocrystals their upcon...

The excited state absorption upconversion of Pr(0.5)Yb(3):ZBLAN glass material, under two-color excitation of the 960 nm semiconductor laser and the Xe lamp light simultaneously, is reported in this article. It was found that the upconversion emission spectra of 480.1, 519.0, 601.9 and 631.8 nm coincide with the common emission spectra. Meanwhile, the upconversion-excitation spectrum has three obvious peaks under two-color excitation, and they respectively correspond to the 856.0 nm upconversion excitation transition [ 1 G 4 (Pr 3+ )→ 1 I 6 (Pr 3+ ) and 1 G 4 (Pr 3+ )→ 3 P 1 (Pr 3+ )], the 789.0 nm upconversion excitation transition 1 G 4 (Pr 3+ )→ 3 P 2 (Pr 3+ ), and the 803.7 nm upconversion excitation transition 3 H 6 (Pr 3+ )→ 1 D 2 (Pr 3+ ). The upconversion excitation transition 1 G 4 (Pr 3+ )→ 1 I 6 (Pr 3+ ) is strong because its oscillator strength f = 23.040×10 −6 is large, which results in a large peak appearing in the upconversion excitation spectrum. That is just the new interesting two-color excitation upconversion luminescence phenomenon of Pr(0.5)Yb(3):ZBLAN induced by one laser and one continuous normal light simultaneously.
