| 1 | Diode-pumped wavelength-switchable visible Pr^(3+):YLF laser and vortex laser around 670 nm显示文摘Here we developed a novel wavelength-switchable visible continuous-wave(CW)Pr^(3+):YLF laser around 670 nm.In single-wavelength laser operations,the maximum output powers of 2.60 W,1.26 W,and 0.21 W,the maximum slope efficiencies of 34.7%,27.3%,and 12.3%were achieved with good beam qualities(M^(2)<1.6)at 670.4 nm,674.2 nm,and 678.9 nm,respectively.Record-high output power(2.6 W)and record-high slope efficiency(34.7%)were achieved for the Pr^(3+):YLF laser operation at 670.4 nm.This is also the first demonstration of longer-wavelength peaks beyond 670 nm in the^(3)P_(1)→^(3)F_(3)transition of Pr^(3+):YLF.In multi-wavelength laser operations,the dual-wavelength lasings,including 670.1/674.8 nm,670.1/679.1 nm,and 675.0/679.4 nm,were obtained by fine adjustment of one/two etalons within the cavity.Furthermore,the triple-wavelength lasings,e.g.672.2/674.2/678.6 nm and 670.4/674.8/679.4 nm,were successfully demonstrated.Moreover,both the first-order vortex lasers(LG_(0)^(+1)and LG_(0)^(-1)modes)at 670.4 nm were obtained by off-axis pumping. | Xiuji Lin Qichen Feng Yao Zhu Shuaihao Ji Bo Xiao Huiying Xu Wensong Li Zhiping Cai | 2021 | Opto-Electronic Advances2021，4，4： | 4 |

| 4 | High performance visible generation of Ho^(3+)-doped all-fiber lasers显示文摘Direct generation of visible frequency from a compact all-fiber laser while preserving high output characteristics has been a subject of research in laser technology.We investigated the high output performance of all-fiber lasers based on Ho^(3+)-doped ZBLAN fluoride glass fiber especially operating in the deep-red band by pumping at 640 nm.Remarkably,we achieved a maximum continuous-wave output power of 271 m W at 750 nm with a slope efficiency of 45.1%,which represents,to our knowledge,the highest direct output power recorded in an all-fiber laser with a core diameter of less than 10μm in the deep-red band.Additionally,we successfully developed a 1.2μm all-fiber laser pumped by a 640 nm laser.We extensively investigated the correlation between these two-laser generation processes and their performances at 750 nm and 1.2μm wavelengths.By increasing the pumping rate,we observed an efficient recycling of population through a highly excited state absorption process,which effectively returned the population to the upper laser level of the deep-red transition.Moreover,we determined the optimized conditions for such lasers,identified the processes responsible for populating the excited state energy levels,and established the corresponding spectroscopic parameters. | SHUAIHAO JI XUEXIAN LIN BO XIAO ZHONGYU WANG XIUJI LIN ZHIPING CAI | 2023 | Photonics Research2023，11，12： | 0 |
| 5 | Hydrogen storage performance of LaNi_(3.95)Al_(0.75)Co_(0.3) alloy with different preparation methods显示文摘Rare-earth AB5-type La–Ni–Al hydrogen storage alloys are widely studied due to their extensive application potentials in hydrogen isotope storage,hydrogen isotope isolation and hydrogen compressors,etc.Good hydriding/dehydriding kinetics,easily activation,high reversibility are important factors for their practical application.However,their overall hydrogen storage performance,especially plateau pressure and hydrogen absorption/desorption durability need to be further optimized.In this study,the microstructures and the hydrogen storage properties of as-cast,annealed,and melt-spun LaNi_(3.95)Al_(0.75)Co_(0.3) alloys were investigated.The experimental results of XRD and SEM showed that all alloys contained a pure CaCu5 type hexagonal structure LaNi_(4)Al phase.The cell volume increased in an order of annealed>melt-spun>as-cast,resulting in a lower hydrogen absorption/desorption plateau pressure and a more stable hydride phase.The hydrogen storage capacity of three alloys was almost the same.The slope factor of the annealed and melt-spun alloys is smaller than the as-cast alloy,indicating that heat-treatment process can make the alloys more uniform.For the cycle stability of the alloys,the hydrogen absorption rate of the annealed alloy and melt-spun alloy was much faster than that of the as-cast alloy after 500 cycles.The melt-spun alloy showed high pulverization resistance during hydrogen absorption/desorption,and exhibited an excellent cycling retention of 99%after 500 cycles,suggesting that melt-spinning process can enhance the cycle stability and improve the cycle life of the alloy. | Lijun Lv Jian Lin Guo Yang Zhaowei Ma Linhua Xu Xiujie He Xingbo Han Wei Liu | 2022 | Progress in Natural Science:Materials International2022，32，2： | 0 |
