“…As introducing F − ions into our TWZ glass, σ em decreases slightly from 1.42 to 1.38 pm 2 but τ f and the product σ em τ f increases evidently from 0.91 ms and 1.29 pm 2 ms to 1.14 ms and 1.57 pm 2 ms respectively; moreover, the minimum pump intensity I min decreases from 1.16 to 1.09 kW/cm 2 (in Tables 2 and 3). Comparing with other known laser glasses (QX, ADY, LY, PN, FP) [5,6,[10][11][12], the glass TWZF has excellent potential laser properties, which close to PN glasses and better than other known glasses as shown in Table 3. Therefore, we believe that TWZF glass is a promising laser host matrix for high power generation.…”

“…Recently, the literature reported that Yb-doped tellurite glasses have more advantages over some other excellent laser glasses [8,9]: large absorption and emission cross-section, high Ybdoped concentration, wide fluorescence effective linewidth. Nevertheless, the lifetime of Yb 3+ in tellurite host is much lower than other hosts such as QX, ADY, LY, PN and FP glasses and becomes a defect for laser host [5,6,[10][11][12]. In order to increase the laser efficiency of a particular transition, the emission cross-section and the fluorescence lifetime should be made as large as possible.…”

Two series of Yb3+ -doped silica glasses (YA and YAP) are fabricated using the sol-gel method, and their spectroscopic properties are investigated. The longest fluorescence lifetime of 0.96 ms is obtained in YAP2 and YAP3 glasses. The emission cross-section (σemi) and σemi × τ of Yb 3+ in the YAP1 glass are 1.00 pm 2 and 0.94 pm 2 ·ms, respectively. Co-doping with Al and P decreases the hydroxyl group content in the glasses because of the reduction in non-bridging oxygen content. The lowest OH content in the YAP3 glass is 9.6 ppm.OCIS codes: 160. 5690, 160.6060, 160.6030, 160.4760. doi: 10.3788/COL201210.081601.Over the last few years, Yb-doped silica glass has attracted increasing interest for high power and short pulse laser applications [1−3] . Yb ions have advantages, such as high efficiency as well as broad absorption and emission bands. The high quantum efficiency of Yb 3+ leads to low thermal loading in laser materials [4] . Theoretically, Yb 3+avoids excited state absorption and upconversion energy transfer because of its simple energy level structure with only two electronic multiplets ( 2 F 5/2 and 2 F 7/2 ). Moreover, Yb ions have long fluorescence lifetimes, which provide the benefit of energy storage. Compared with multi-component glasses, such as phosphate, borate, and gallium glasses that have high emission cross sections [5] , silica glasses have their own advantages, including low thermal expansion coefficient, good high-temperature and thermal shock resistance, high mechanical strength, and stable chemical properties. However, systematic investigations on the optical properties of Yb 3+ -doped silica glasses are few [6,7] . In this letter, silica glass is selected as the matrix for Yb 3+ doping. Most rare-earth-doped silica fiber preforms are well known to be fabricated using the traditional modified chemical vapor deposition (MCVD) method combined with solution doping [8,9] . However, the MCVD method has its geometrical and rare earth ion doping level limitations [10] , and achieving high Yb-doped silica is difficult [11−13] . The sol-gel process is available for the fabrication of silica glass at low cost and using simple equipment. Different species can be mixed at the molecular scale through the sol-gel process [14] , so that high Yb ion doping in silica and good homogeneity can be achieved. However, high Yb 3+ ion doping produces clusters and defects, which are extremely harmful to emission and laser properties. Co-doping with Al and P can effectively suppress the cluster formations of Yb ions [15] . In this letter, the sol-gel method was used to prepare Yb 3+ -doped silica glasses. The physical and spectroscopic characteristics of the Yb 3+ -doped silica glasses through the sol-gel method were investigated in detail.Reagent grade chemical reagents were used as starting materials. Tetraethoxysilane was used as the precursor of SiO 2 . AlCl 3 ·6H 2 O, YbCl 3 ·6H 2 O, and H 3 PO 4 were used for the realization of Al 2 O 3 , Yb 2 O 3 , and P 2 O 5 doping, respectively. Ethanol was used as t...
