“…However, a saturation behavior was observed in this experiment and was thought to be caused by competing laser transition 4 S 3/2 → 4 I 13/2 at 850 nm. Allain et al [126] demonstrated a 50 mW tunable (540 nm-545 nm) green fiber laser in which the drawback of favoring oscillation of 850 nm was avoided by shifting the pump wavelength to 970 nm. Pumping at 970 nm eliminates the competitive lasing because there is no ESA from 4 I 13/2 at this wavelength.…”

-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.

“…Er 3+ ions doped in various laser hosts emit the 1.55 µm fluorescence through the 4 I 13/2 → 4 I 15/2 transition, which has a wide application, for example, coherent laser radar, laser measurement distance, eye-safe laser and optical communication technology [1], and lasing at the green transition 4 S 3/2 → 4 I 15/2 has led to fruitful results with fiber and bulk structures [2,3]. La 3 Ga 5 SiO 14 crystal belongs to the point group 32, space group P321 [4][5][6][7].…”

Single crystals of Erbium (Er) doped La 3 Ga 5 SiO 14 (LGS) have been grown along c-axis by using the Czochralski method. The absorption and fluorescence spectra of LGS: Er 3+ single crystals have been measured and analyzed according to the Judd-Ofelt theory. When applied, the following spectral parameters have been obtained: intensity parameters Ω t , Ω 2 = 2.741674×10-20 cm 2, Ω 4 = 0.66934×10 -20 cm 2 and Ω 6 = 0.592591×10 -20 cm 2 , radiative transition probabilities A J,J" , P J,J" . The radiative lifetime of levels 4 I 13/2 , 4 H 9/2 , 4 S 3/2 are 11.333ms, 0.447ms and 0.704ms, respectively. The fluorescence branching ratios and the integrated emission cross sections are also calculated. The results suggest that LGS: Er crystals have potential applications as a laser material.

“…Glasses as laser hosts have advantages to form fibres more easily than single crystals and RE ions-doped glass fibre lasers have been applied in optical communication, optical fibre sensing, displays, medical treatment, etc. However, in the last decades, green fibre lasers was mainly achieved by using Er 3+ -doped glass fibres by upconversion luminescence process [4,5]. The green-pulsed laser operation based on 5 D 4 → 7 F 5 transition of Tb 3+ was first reported in 1967 [6].…”

In this paper, for the first time, the visible fluorescence properties, resonance energy transfer mechanism responsible for non-radiative decay rates of 5 D 4 → 7 F 5 transition and also quenching of fluorescence intensity of the 5 D 3 → 7 F 5 transition of various concentrations of Tb 3+ ions in LBZLFB glasses are reported. Optical absorption, fluorescence spectra and quantum efficiencies are measured and analysed. Green fluorescence related to 5 D 4 → 7 F 5 (548 nm) transition is registered under excitation of 378 nm of Tb 3+ ions. Based on excitation and fluorescence measurements, several spectroscopic parameters for Tb 3+ ions are examined as a function of concentration by Judd-Ofelt theory to judge the suitability of studied glasses for display devices and fibre lasers.
