“…It is therefore an excellent host material for constructing single and high repetition frequency fiber lasers. Yao et al measured the transmission spectrum of 2-mm-thick glass samples after they were immersed in deionized water for 12 days [52], and the results are shown in Figure 3. There was no obvious change in the transmission spectra, and no hydrated layer was formed at the end face of the tellurite glass, which proves its great resistance to water.…”

“…Several researchers have studied the reduction of water molecules and hydroxyl groups, in order to further improve the performance of tellurite glass materials used in midinfrared fiber lasers. Specific test procedures included melting the glass in a dry atmosphere, raw material dehydration, and the use of fluoride [52] or chloride raw materials [53], as eliminating hydroxyl groups diminishes loss (at specific wavelengths) and is therefore favorable for the commercialization of tellurite glass fibers.…”

“…The same authors used a tapered allsolid fluorotellurite fiber with ultra-high NA to generate an SC output spectrum covering the entire 0.4-5 μm transmission window and pumped using a 1560-nm mode-locked fiber laser [88]. Yao et al achieved stable 10.4 W SC generation in the wavelength ranging from 947 to 3934 nm from a TBY-based all-solid fluorotellurite fiber when pumped using a high-power 1980 nm femtosecond fiber laser [52]; when the average pump power was increased to 1.1 W, large spectral broadening occurred as shown in Figure 22(a). Because the fiber was pumped at anomalous dispersion regime, the spectral broadening for a pump power of ≥1.1 W originated from the SPM, the formation of higher-order soliton, soliton fission, soliton self-frequency shift (SSFS), and the generation of blue-shifted dispersive waves.…”

Herein, the efficiently high‐power pulsed Raman lasers with wavelength above 2.1 μm are experimentally demonstrated relying on the stimulated Raman scattering. A tailored high‐power noise‐like pulse (NLP) fiber laser system centered at ≈1953 nm with a maximum output power of ≈10.9 W is served as the pump source. By directly pumping a section of highly Ge‐doped silica fiber, the first pulsed Raman laser (centered at≈2139 nm) and the second pulsed Raman laser (centered at ≈2353 nm) with maximum output powers of ≈3.8 and ≈0.25 W are obtained, respectively, which represent the highest output powers of NLP at these wavelength regions, to the best of knowledge. Moreover, a high spectral purity of ≈94.3% of the first Raman laser is obtained, which indicates the significantly potential application of NLP in pulsed Raman laser. The midinfrared NLP fiber laser source will have potential applications in transparent polymer materials processing and midinfrared spectroscopy.

Supercontinuum (SC) sources covering near‐infrared and midinfrared region have attracted enormous interest and found significant applications in tissue imaging, sensing, spectroscopy, defense, and environmental monitoring. Herein, an 8.45 W all‐fiber ultraflat SC source with a spectral range of 1.01–4.05 μm using a flat high‐power 1.9–2.7 μm SC fiber source to pump a piece of fluorotellurite fiber is presented. The SC spectrum exhibits a 3 dB bandwidth of 1850 nm, ranging from 1870 to 3720 nm, and a 10 dB bandwidth of 2770 nm, ranging from 1120 to 3890 nm. The measured power stability is 0.19% (root mean square) for 5 h of continuous operation, proving the excellent power stability of the system. To the best of knowledge, the SC spectrum exhibits the widest reported 3 and 10 dB bandwidths for 1–4 μm SC sources.
