“…The used initial high-purity substances and the technique for preparation of glasses in the closed chamber make it possible to produce tellurite glasses with the total content of 3d-transition metals of less than 0.1–2 ppm wt and with undesirable rare-earth elements concentration less than the detection limit of the laser mass spectrometry (<1–2 ppm wt) 30,31 . The technique of the preparation of high-quality, stable against crystallization, ultradry tellurite glasses was developed previously and described in detail in 17,19 .…”

“…The monolithic preform for fiber production was fabricated by the technique of melt extrusion, the method is similar to that described in 17 . Further, we produced step-index multimode and single-mode (with estimated cutoff wavelength of ~1.95 μm) fibers with core/cladding diameters of 50/157 μm and 8/100 μm, respectively.…”

“…Tellurite glasses have a higher phonon energy, but they are stronger mechanically and possess better chemical stability 16 . Many compositions among the most actively investigated zinc-tellurite and tungstate-tellurite systems are resistant to crystallization 17–19 . Laser generation at 2.3 μm in a bulk Tm-doped tellurite glass sample was recently demonstrated by Denker et al 20,21 .…”

Ultrabroadband amplification and two-color CW lasing simultaneously near 1.9 μm and 2.3 μm in a Tm3+-doped tellurite fiber were demonstrated experimentally, for the first time to the best of our knowledge. A low-loss Tm3+-doped core fiber from TeO2–ZnO–La2O3–Na2O glasses stable against crystallization was produced by a special technique, providing a low concentration of hydroxyl groups. Supercontinuum from a highly GeO2 doped silica fiber pumped by an Er fiber laser system was used as a seed for an amplifier. A maximum gain of 30 dB and 7 dB was measured at 1.9 μm and 2.3 μm, respectively. We report detailed experimental and theoretical studies, which are in a very good agreement, of laser amplification and generation in the manufactured fiber with carefully measured and calculated parameters. A quantitatively verified numerical model was used to predict power scalability at 2.3 μm in schemes with optimized parameters at increased pump power. The presented results show that a high-quality tellurite fiber is a promising candidate for developing lasers in the 2.3 μm atmospheric window which are particularly relevant for applications in gas sensing, eye-safe laser radars, breath analysis, remote sensing and stand-off trace gas detection.

“…Undoped highly nonlinear 72TeO 2 -24WO 3 -4La 2 O 3 glass was produced using a procedure described in detail in [27,28] by melting the initial components (TeO 2 , WO 3 , and La 2 O 3 oxides) inside a sealed silica chamber in the purified O 2 atmosphere. The glass was synthesized in a platinum crucible for a few hours with periodic stirring of the glass-forming melt.…”

Compact fiber-based sources generating optical pulses with a broadband spectrum in the mid-IR range are in demand for basic science and many applications. Laser systems producing tunable Raman solitons in special soft-glass fibers are of great interest. Here, we report experimental microstructured tellurite fibers and demonstrate by numerical simulation their applicability for nonlinear soliton conversion in the mid-infrared (-IR) range via soliton self-frequency shift. The fiber dispersion and nonlinearity are calculated for experimental geometry. It is shown numerically that there are two zero dispersion wavelengths for the core size of 2 μm and less. In such fibers, efficient Raman soliton tuning is attained up to a central wavelength of 4.8 μm using pump pulses at 2.8 μm.
