“…in the glass doped with 0.15Nd 3+ :0.45Yb 3+ a broad (∆λ = 100 nm) luminescence band in the vicinity of 1 µm was obtained. Its half-intensity width is almost three times larger than in case of the glass doped with neodymium ions [33,34]. This phenomenon is connected with the non-radiative resonance interaction between rare earth ions.…”

Abstract. The article brings into focus the present state of technology employing active fibres doped with rare earth (RE) ions for applications requiring power supply of several dozen watts and broadband ASE sources. Current trends in development of glasses and in construction of active fibres used in fibre sources of radiation within VIS-NIR range are presented. Technological constraints in the doping of fibre core glasses are discussed, with particular consideration of optimal RE concentration for technical applications. Characteristics of glasses are offered, and the glasses are used for manufacturing optical fibres with luminescence within the visible as well as near-and mid-infrared ranges. Also, requirements and luminescence properties concerning glasses co-doped with e.g. Nd 3+ /Yb 3+ ,Tm 3+ /Ho 3+ and Yb 3+ /Tb 3+ are discussed. Results of research on the impact of technological parameters of glass matrices on luminescence properties of core glasses and optical fibres are quoted. For the doped glasses of which luminescence in a wide spectral range is desired, conditions for their processing into optical fibre systems are mentioned. Additionally, the impact of phonon energy in the glass on producing emission in a specified spectral range is analyzed. Furthermore, the article presents directions of technological studies to solve problems persisting in the phase of glass matrix design, as well as in determining the influence of fibre drawing process on the luminescence properties of core glasses and optical fibres, confirming the differences in luminescence stemming from the drawing process. Finally, some original designs of core glasses and active multicore fibre systems devised for construction of fibre radiation sources are presented.

“…The high concentration of ytterbium in the matrix results in strong radiation absorption at the wavelength of 978 nm, thus facilitating efficient excitation of the Yb 3+ /Tm 3+ system. In practice, because of the excitation bandwidth and high quantum efficiency (≈ 90%), Yb 3+ ions are used as sensitizers in upconversion systems [5,7].…”

“…Low phonon energy in telluride glasses (≈ 750 cm −1 ) has an impact on the reduced effect of multiphonon relaxation, thus preventing high radiant emission to be obtained. Therefore, telluride glasses are usually applied in optical waveguides [2][3][4][5][6]. Solid-body lasers emitting radiation within the blue wavelength range are commonly used nowadays in data recording/reading systems in HD quality, colour displays or diagnostic medicine.…”

The paper presents luminescence properties of telluride glass doped with Yb 3+ /Tm 3+ ions. Strong blue emission at 477 nm corresponding to the transition 1 G 4 → 3 H 6 in thulium ions was measured under the excitation of a 976 nm diode laser. The dependence of the upconversion emission upon the thulium ions concentration was studied in order to determine the optimal ion content. The results showed that intensity of upconversion emission enhances, with the increase of Tm 3+ content up to 0.1 mol.%. The most effective energy transfer Yb 3+ → Tm 3+ occurs in the glassy matrix with molar ratio of dopant 1 Yb 3+ : 0.1 Tm 3+ . Double-clad optical fibre was made of glass with the highest upconversion intensity at the wavelength of λ = 477 nm (TGPF101). As a result of optical excitation (λ = 976 nm) of the produced optical fibre, an additional emission line, which was not noticed in the glass, was observed at the wavelength of 351 nm corresponding to the 1 D 2 → 3 H 6 transition.
