1Status and development of high-power laser facilities at the NLHPLP显示文摘In this paper, we review the status of the multifunctional experimental platform at the National Laboratory of High Power Laser and Physics(NLHPLP). The platform, including the SG-II laser facility, SG-II 9th beam, SG-II upgrade(SG-II UP) facility, and SG-II 5 PW facility, is operational and available for interested scientists studying inertial confinement fusion(ICF) and a broad range of high-energy-density physics. These facilities can provide important experimental capabilities by combining different pulse widths of nanosecond, picosecond, and femtosecond scales. In addition, the SG-II UP facility, consisting of a single petawatt system and an eight-beam nanosecond system, is introduced including several laser technologies that have been developed to ensure the performance of the facility. Recent developments of the SG-II 5 PW facility are also presented.Jianqiang Zhu Jian Zhu Xuechun Li Baoqiang Zhu Weixin Ma Xingqiang Lu Wei Fan Zhigang Liu Shenlei Zhou Guang Xu Guowen Zhang Xinglong Xie Lin Yang Jiangfeng Wang Xiaoping Ouyang Li Wang Dawei Li Pengqian Yang Quantang Fan Mingying Sun Chong Liu Dean Liu Yanli Zhang Hua Tao Meizhi Sun Ping Zhu Bingyan Wang Zhaoyang Jiao Lei Ren Daizhong Liu Xiang Jiao Hongbiao Huang Zunqi Lin 2018High Power Laser Science and Engineering2018,6,4:8
2Studies of Primary Angle Qosure Glaucoma in China显示文摘The resent researches on primary angle closure glaucoma (PACG) in China were reviewed. The prevalence of PACG (0.41%) in chinese is between the Caucasian and Eskimos, and chronic type is the dominant type in PACG. However, with the economic development and medical care improvements, the prevalence condition of PACG may change; several researches discovered that the mechanism of PACG, especially the chronic type, is not only because of pupil-blocking but also closely related to the mechanism of crowding of peripheral iris and the anterior location of the ciliary body. We supposed that PACG can be divided into several subtypes based on this machnism. Also, we believe that the use of ultrasound biomicroscopy (UBM) and ophthalmic laser in China has promoted the research of PACG and improved the level of prevention and treatment of PACG.

3Quantitative Real Time Measurement of Iris Configuration in Human Eyes显示文摘Purpose: To evaluate intraobserver and interobserver reproducibility of real time measurement of iris morphology in living human eyes.Methods: Base on the platform of software (Autocad, version 12), we developed an ultrasound biomicroscopy (UBM) image asisstant measuring system. By using the system, we can perform the iris configuration quantitative measurement in living eyes. The measuring parameters including: iris rest length,radius of iris curvature,and the thickness in different parts of iris. Ten anterior segment images of one normal individual were obtained by a single operator to evaluate the intraobserver reproducibility of image capture, and ten times measurement of one image were performed by a single operator to assess the reproducibilityof image measurement. The measurement of three independent observers were compared to investigate interobserver reproducibility in quantitative measurement. Intraobserver and interobserver reproducibility of measurement were assessed by calculating theNingli Wang, Mingying Lai, Wenbin ZhouZhongshan Ophthalmic Center , Sun Yat-sen University of Medical Sciences , Guangzhou 510060 , China 1997眼科学报1997,13,1:6
4Single-shot ultrafast multiplexed coherent diffraction imaging显示文摘Classic interferometry was commonly adopted to realize ultrafast phase imaging using pulsed lasers;however, the reference beam required makes the optical structure of the imaging system very complex, and high temporal resolution was reached by sacrificing spatial resolution. This study presents a type of single-shot ultrafast multiplexed coherent diffraction imaging technique to realize ultrafast phase imaging with both high spatial and temporal resolutions using a simple optical setup, and temporal resolution of nanosecond to femtosecond scale can be realized using lasers of different pulse durations. This technique applies a multiplexed algorithm to avoid the data division in space domain or frequency domain and greatly improves the spatial resolution. The advantages of this proposed technique on both the simple optical structure and high image quality were demonstrated by imaging the generation and evaluating the laser-induced damage and accompanying phenomenon of laser filament and shock wave at a spatial resolution better than 6.96 μm and a temporal resolution better than 10 ns.YINGMING XU XINGCHEN PAN MINGYING SUN WENFENG LIU CHENG LIU JIANQIANG ZHU 2022Photonics Research2022,10,8:2
5Target alignment in the Shen-Guang Ⅱ Upgrade laser facility显示文摘The Shen-Guang II Upgrade(SG-Ⅱ-U) laser facility consists of eight high-power nanosecond laser beams and one shortpulse picosecond petawatt laser. It is designed for the study of inertial confinement fusion(ICF), especially for conducting fast ignition(FI) research in China and other basic science experiments. To perform FI successfully with hohlraum targets containing a golden cone, the long-pulse beam and cylindrical hohlraum as well as the short-pulse beam and cone target alignment must satisfy tight specifications(30 and 20 μm rms for each case). To explore new ICF ignition targets with six laser entrance holes(LEHs), a rotation sensor was adapted to meet the requirements of a three-dimensional target and correct beam alignment. In this paper, the strategy for aligning the nanosecond beam based on target alignment sensor(TAS) is introduced and improved to meet requirements of the picosecond lasers and the new six LEHs hohlraum targets in the SG-II-U facility. The expected performance of the alignment system is presented, and the alignment error is also discussed.Lei Ren Ping Shao Dongfeng Zhao Yang Zhou Zhijian Cai Neng Hua Zhaoyang Jiao Lan Xia Zhanfeng Qiao Rong Wu Lailin Ji Dong Liu Lingjie Ju Wei Pan Qiang Li Qiang Ye Mingying Sun Jianqiang Zhu Zunqi Lin 2018High Power Laser Science and Engineering2018,6,1:2
6First radiative shock experiments on the SG-II laser显示文摘We report on the design and first results from experiments looking at the formation of radiative shocks on the ShenguangII(SG-II)laser at the Shanghai Institute of Optics and Fine Mechanics in China.Laser-heating of a two-layer CH/CH–Br foil drives a∼40 km/s shock inside a gas cell filled with argon at an initial pressure of 1 bar.The use of gas-cell targets with large(several millimetres)lateral and axial extent allows the shock to propagate freely without any wall interactions,and permits a large field of view to image single and colliding counter-propagating shocks with time-resolved,pointprojection X-ray backlighting(∼20µm source size,4.3 keV photon energy).Single shocks were imaged up to 100 ns after the onset of the laser drive,allowing to probe the growth of spatial nonuniformities in the shock apex.These results are compared with experiments looking at counter-propagating shocks,showing a symmetric drive that leads to a collision and stagnation from∼40 ns onward.We present a preliminary comparison with numerical simulations with the radiation hydrodynamics code ARWEN,which provides expected plasma parameters for the design of future experiments in this facility.Francisco Suzuki-Vidal Thomas Clayson Chantal Stehlé Uddhab Chaulagain Jack W.D.Halliday Mingying Sun Lei Ren Ning Kang Huiya Liu Baoqiang Zhu Jianqiang Zhu Carolina De Almeida Rossi Teodora Mihailescu Pedro Velarde Manuel Cotelo John M.Foster Colin N.Danson Christopher Spindloe Jeremy P.Chittenden Carolyn Kuranz 2021High Power Laser Science and Engineering2021,9,2:1

9Design and performance of final optics assembly in SG-ⅡUpgrade laser facility显示文摘In high power laser facility for inertial confinement fusion research, final optics assembly(FOA) plays a critical role in the frequency conversion, beam focusing, color separation, beam sampling and debris shielding. The design and performance of FOA in SG-II Upgrade laser facility are mainly introduced here. Due to the limited space and short focal length, a coaxial aspheric wedged focus lens is designed and applied in the FOA configuration. Then the ghost image analysis,the focus characteristic analysis, the B integral control design and the optomechanical design are carried out in the FOA design phase. In order to ensure the FOA performance, two key technologies are developed including measurement and adjustment technique of the wedged focus lens and the stray light management technique based on ground glass.Experimental results show that the design specifications including laser fluence, frequency conversion efficiency and perforation efficiency of the focus spot have been achieved, which meet the requirements of physical experiments well.Zhaoyang Jiao Ping Shao Dongfeng Zhao Rong Wu Lailin Ji Li Wang Lan Xia Dong Liu Yang Zhou Lingjie Ju Zhijian Cai Qiang Ye Zhanfeng Qiao Neng Hua Qiang Li Wei Pan Lei Ren Mingying Sun Jianqiang Zhu Zunqi Lin 2018High Power Laser Science and Engineering2018,6,2:1

11Coupled attitude-vibration analysis of an E-sail using absolute nodal coordinate formulation显示文摘In this study,the effects of solar wind on an electric sail(E-sail)are modeled and analyzed using an absolute nodal coordinate formulation(ANCF).First,the thrust of the charged metal tether that makes up the E-sail was analyzed and a model was established.Numerical simulations of a single metal tether were performed.Then,an overall E-sail model was established using the connection matrix,and E-sails subjected to different angular velocities were compared.Simulation results of the ANCF model and a dumbbell model were compared at different angular velocities.The results confirm that with a relatively high angular velocity,the flexible metal chain can be approximately regarded as a rigid body.However,with a small angular velocity,the flexibility of the metal chain cannot be ignored.Ce Zhao Mingying Huo Ji Qi Shilei Cao Dongfang Zhu Lujun Sun Hongli Sun Naiming Qi 2020Astrodynamics2020,4,3:0
12Environmental factors affecting regional differences and decadal variations in the buried flux of marine organic carbon in eastern shelf sea areas of China显示文摘To characterize environmental factors controlling decadal-scale variations in the buried flux of marine organic carbon(BFC_(m))in the eastern shelf sea areas of China(ECSS),four well preserved sediment cores collected from the central Yellow Sea mud(CYSM)area,the Yellow Sea Coastal Current(YSCC)area and the Changjiang River Estuary(CRE)were investigated in this study.In the CYSM,variations in BFC_(m) were found to be dependent on variations in primary productivity and to exhibit a cyclical trend possibly related to fluctuations in the Pacific Decadal Oscillation(PDO)and the East Asian winter monsoon index(EAWM).In the YSCC,BFC_(m) likewise depends on primary productivity.Prior to the 1950s,variations in BFC_(m) were similar to that of the EAWM.After the 1950s,BFC_(m) increased rapidly and exhibited maximum values in the surface layer,consistent with an increase in primary productivity caused by the input of terrestrial nutrients associated with China’s economic development.In the CRE,variations in BFC_(m) were affected by several competing factors making it difficult to identify clear relationships between variations in BFC_(m) and primary productivity.In contrast,long-term variability in BFC_(m) is more similar to changes in the Changjiang River sediment load.Thus,it is speculated that the construction of dams along the Changjiang River may be the main cause of variations in BFC_(m) in this area.Given the disproportionate effects of human activities on marine environments and decadal variations in BFC_(m) in the ECSS,careful attention should be paid to regional differences in organic carbon preservation and environmental changes lest estimates of these values be made imprecise or inaccurate.Qian Yang Keming Qu Shu Yang Yao Sun Yan Zhang Mingying Zhou 2021Acta Oceanologica Sinica2021,40,6:0
