2BaYOBO_(3):A deep-ultraviolet rare-earth oxy-borate with a large second harmonic generation response显示文摘Deep-ultraviolet(UV)nonlinear optical(NLO)crystals with excellent performances are of great importance in laser science and technology.However,to design and synthesize an ideal deep-UV NLO material with a balance between second harmonic generation(SHG)response and UV cut-off edge is still a huge challenge.Herein,a new oxy-borate BaYOBO_(3)(BaYBO)was designed and synthesized by substituting Be^(2+)with Y^(3+)from Sr_(2)Be_(2)B_(2(O_(7).The BaYBO features a stable three-dimensional framework and satisfies the property balance between a large SHG response(~2.6×KH_(2)PO_(4)KDP))and a short UV cut-off edge(<190 nm)as a promising deep-UV NLO candidate.The study of structure-property relationship indicates that the large SHG response of BaYBO is mainly attributed to the coplanar arrangement and large number density of BO_(3 )triangles.These results demonstrate that substituting Be^(2+)with Y^(3+)cations is also a feasible strategy for developing new deep-UV NLO crystals.Mengen Gao Hongping Wu Hongwei Yu Zhanggui Hu Jiyang Wang Yicheng Wu 2021Science China Chemistry2021,64,7:1

9Hydrothermal growth of KTiOPO_(4) crystal for electro-optical application显示文摘'New'electro-optical(EO)crystals are hard to find,'old'EO crystals are scarce and each has its own problems,and the demand for high-performance EO crystals by higher power,higher repetition rate,and narrower pulse width laser is realistic and urgent.The EO performance of KTP was recognized as soon as it was discovered,but after more than 40 years of development,the reports,and products of EO devices based on KTP are less than those of other EO crystals,even though KTP is now almost the cheapest nonlinear optical crystal material.In this paper,based on our understanding of the crystal structure of predecessors and ourselves,especially the understanding and practice of quasi-one-dimensional ionic conduction mechanism,we think that crystal growth is the most important reason that affects the controllability of crystal performance.Through a series of science and technology,we realize the growth of large-size crystals with high-optical uniformity,then reduce the absorption of KTP to a very low level,and grow crystals with resistance to electric damage and laser damage.On this basis,reducing the conductivity and improving the uniformity of optical,electrical,piezoelectric,and ferroelectric properties are emphasized.The extinction ratio,piezoelectric ringing effect,and thermal influence of the EO switch based on KTP crystal are tested,and some publicly available progress of using KTP EO devices in high-repetition rate laser is listed.Finally,we are looking forward to the development of KTP EO crystal for the laser system to EO generator for integrated optics.Haitao Zhou Xiaoling He Wenyuan Wu Jingfang Tong Jinliang Wang Yanbin Zuo Yicheng Wu Changlong Zhang Zhanggui Hu 2023Light(Science & Applications)2023,12,1:1

11Synthesis of Polycrystalline Nd∶YAG Nanopowders Used for Sintering Transparent Ceramics via Gel Combustion显示文摘Polycrystalline nano-sized neodymium doped yttrium aluminum garnet (Nd∶Y3Al5O12, Nd∶YAG) powders were synthesized via a gel combustion method using nitrates and citric acid as starting materials. The evolution of phase composition and micro-structure of the powders were characterized by X-ray powder diffraction, thermogravimetry/differential thermal analysis and scanning electron microscopy. Well-crystallized Nd∶YAG nano-sized powders could be obtained at 950 ℃ for 2 h. The resultant powders are well dispersed, have a relatively narrow size distribution with an average particle size of approximately 50 nm, and show excellent sinterability. These powders can be densified to 99.2% of the theoretical density by HP sintering at 1700 ℃ for 3 h under 20 MPa nitrogen pressure.Li Xianxue Hu Zhanggui Li Jiangtao 2006Journal of Rare Earths2006,24,z1:0

13Broadband 1T-polytype tantalum disulfide saturable absorber for solid-state bulk lasers显示文摘1T-polytype tantalum disulfide(1T-TaS_(2)),an emerging strongly correlated material,features a narrow bandgap of 0.2 e V,bridging the gap between zero-bandgap graphene and large-bandgap 2D nonlinear optical(NLO)materials.Combined with its intense light absorption,high carrier concentration,and high mobility,1T-TaS_(2) shows considerable potential for applications in broadband optoelectronic devices.However,its NLO characteristics and related applications have rarely been explored.Here,1T-TaS_(2) nanosheets are prepared by chemical vapor deposition.The ultrafast carrier dynamics in the 400–1100 nm range and broadband NLO performance in the 515–2500 nm range are systematically studied using femtosecond lasers.An obvious saturable absorption phenomenon is observed in the visible to IR range.The nonlinear absorption coefficient is measured to be-22.60±0.52 cm MW-1under 1030 nm,which is larger than that of other typical 2D saturable absorber(SA)materials(graphene,black phosphorus,and MoS_(2))under similar experimental conditions.Based on these findings,using 1T-TaS_(2) as a new SA,passively Q-switched laser operations are successfully performed at 1.06,1.34,and 1.94μm.The results highlight the promise of 1T-TaS_(2) for broadband optical modulators and provide a potential candidate material system for mid-IR nonlinear optical applications.MENGXIA WANG HAILONG QIU TIANWEN YANG ZHENGPING WANG CHUANRUI ZHAO YUANAN ZHAO TING YU YUYAO JIANG MEILING CHEN YAFEI LIAN GE ZHANG HONGJUN LIU ZHANGGUI HU JIANDA SHAO 2022Photonics Research2022,10,9:0
14Thermal stable and ultralow dielectric loss in(Gd_(0.5)Ta_(0.5))_(x)Ti_(1-x)O_(2)giant permittivity ceramics by defect engineering显示文摘High dielectric loss and poor temperature stability are the current barriers to the application of dielectric materials.In present work,we synthesized a system of acceptor Gd^(3+)and donor Ta^(5+)co-doped(Gd_(0.5)Ta_(0.5))_(x)Ti_(1-x)O_(2)(GTTOx,x=0,0.01,0.02,0.04,0.06)ceramics to enhance dielectric response.It was found that a colossal permittivity(CP,2.65×10^(4)@1 kHz,2.37×10^(4)@1 MHz),a very low dielectric loss(tanδ,0.007@1 kHz,0.03@1 MHz),good stability of frequency(20–10^(6)Hz)and temperature(RT–250°C,Δε′(T)/ε′30<±15%,at 1 kHz)were achieved simultaneously in GTTO0.01 ceramic.Complex impedance spectroscopy,XPS,SEM,and Raman spectroscopy were used to investigate the reasons for the improved dielectric properties.The result indicated that the main reasons for CP and low dielectric loss are the synergistic effect of the electron pinning defect-dipole(EPDD)model,the internal blocking layer capacitance(IBLC)mechanism,and electrode response.This work provides a promising approach for the design of defect-related high-performance giant dielectric ceramics.Jiangtao Fan Gang He Zhenzhu Cao Yongfan Cao Zhen Long Zhanggui Hu 2023Journal of Materiomics2023,9,1:0
