Promising emission behavior in Pr 3+ /In selenide-chalcogenide-glass small-core step index fiber (SIF)

et al. 2017

Selenide-chalcogenide glass, small-core, step-index fiber (SIF), core-doped with Pr 3+ : 9.51 x 10 24 ions m -3 (500 ppmw) is fabricated for the first time with indium to help solubilize Pr 3+ . Core diameters of 20 or 40 µm are confirmed using scanning electron microscopy and near-field imaging; fibre numerical aperture is ~0.4. Optical loss is ≥4.9 dB m -1 across the 3-9m mid-infrared (MIR) spectral range. On pumping at 1.55 m or 2.013 m, the SIFs give broad MIR emission across 3.5-6 m assigned to 3 H6 3 H5 and 3 H5 3 H4. The Pr 3+ emission-lifetime at 4.7 m decreases from bulk-glass (10.1 ±0.3 ms), to intermediately processed fiber (8.10 ±0.5 ms) to SIF (7.1 ±0.5 ms) induced by the processing. On end-pumping SIFs at 2.013 µm, the output pump-power and emission intensity at 4.7 µm became sub-linear and super-linear, respectively, suggesting MIR excited-state saturation is occurring.

a b s t r a c t sСore-clad  bers on the basis of high-purity 1300 ppmw Pr(3+ )-doped Ga-Ge-As-Se and 2000 ppmw Pr(3+ )-doped In-Ge-As-Se-I glasses have been prepared. The minimum optical losses of the  bers are at the level of 1 dB/m in the w avelength range, w here there is no in uence of the praseodym ium absorption. At present, it is the best result obtained for core-clad rare-earth-doped chalcogenide  bers w ith high dopant concentration. The  bers exhibit the broadband luminescence in the spect ral range of 3.5 -5.5 m. The values of luminescence lifetime at the w avelength of 4.7 m are w ithin 6.5-8.2 ms closed to those for the bulk glasses obtained previously. Simulation of laser properties for these core-clad  bers in the three-level cascade scheme w as carried out. The low level of optical losses experimentally achieved in these  bers is one of main criteria for development of mid-IR  ber systems. Int r oduct i onChalcogenide glasses (ChG) doped w ith rare earth elements (REE) are w idely discussed in the scienti c literature regarding the possibility of their using for creation of middle infrared (mid-IR)  ber lasers and ampli ers. At present, laser  ber materials for the spectral region beyond 3.9 m have not been experimentally developed. So, ChGs are of current interest due to their characteristics, such as low phonon energies (dow n to 350 cm -1 ), high transparency in the mid-IR range, potential ultra low optical losses, an ability to dissolve the rare earth elements, as w ell as the high calculated values of the quantum ef ciency and lasing slope ef ciency. To characterize the laser  ber materials, the quantum ef ciency determined as a ratio betw een experimental and calculated values of emission lifetime, the lasing slope ef ciency, and the threshold pow er are used to be considered. These characteristics have been evaluated by numerical simulations for the number of chalcogenide multi-component glasses doped w ith REE, taking into consideration the different pump parameters [1][2][3][4][5][6]. Data show ed the high values of quantum ef ciency (up to 100%) and the lasing slope ef- ciency (up to 54%) of these glasses for the mid-IR range.The main advantages of selenide chalcogenide glasses, as potential laser media, are low phonon energy values (230-300 cm -1 ), the possibility to incorporate the rare earth elements in relatively high concentration (thousands of ppm), high values of refractive index (2.6-2.9, depending on glass composition), and, as a consequence, the high values of absorption cross section at the pump w avelength. The set of these properties of ChGs had predetermined a choice of research subjects here, namely, Pr(3+ )-doped Ga(In)-Ge-As-Se glasses and  bers as the materials promising for mid IR-range.Due to the need to prepare  ber laser materials w ith low optical losses, the main focus had been done on the development of ChGs w ith a low content of limiting impurities w hich have negative in- uence on the spectral characteristics of glasses in the range of ...

In this work, Pr3+ ion‐doped Ge20Ga15−xSbxSe65 (x = 0, 5, 10, in mol%), Ge20Sb15−yInySe65 (y = 5, 10, in mol%), Ge20Ga15−zInzSe65 (z = 0, 5, 10, in mol%), and Ge20Ga5Sb10Se60I5 glasses were prepared. The structural units, thermal properties, and optical properties of these glasses were analyzed. In addition, a comprehensive comparison study of the effects of metal ions (Sb, Ga, and In), S/Se ratio, and I content on the mid‐infrared (MIR) luminescence of Pr3+ ions was conducted. Under a 1.55‐μm laser pump, 0.2 mol% of Pr3+ ion‐doped chalcogenide glasses performed strong photoluminescence in the wavelength range of 3.5‐5.5 μm. Results indicated that the Sb‐containing glass performed the strongest emission intensity among the studied glasses. Moreover, halogen element I can reduce the phonon energy of the matrix, which is beneficial to the luminescence of Pr3+ ions and provide significant possibilities for developing MIR lasers and amplifiers.
