1单程高增益1.9μm光纤气体拉曼激光器显示文摘报道了基于空心光子晶体光纤中氢气分子振动受激拉曼散射(SRS)的单程高增益1.9μm光纤气体激光器。用一个线偏振1064nm亚纳秒脉冲微芯激光器抽运一段长6.5m、充高压氢气的低损耗负曲率空心光纤,实现了到氢气分子一级振动斯托克斯波1907nm的有效转换。气压为2.3MPa时最大能量转换效率大于27%,相应的量子转换效率大于48%,激光平均功率约为10mW,峰值功率大于2000W。为实现高功率、窄线宽、大范围调谐的紧凑型中红外光纤激光器提供了一条潜在的有效途径。王泽锋 于飞 William J Wadsworth Jonathan C Knight 2014光学学报2014,34,8:15
2A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5
3cytoplasmic domain of tissue factor promotes liver fibrosis in mice显示文摘AIM To evaluate the role of tissue factor(TF) and protease activated receptor(PAR)-2 in liver fibrosis.METHODS Using CCl4 administration for eight weeks, we induced hepatic fibrosis in wild-type C57BL/6 mice and in mice with deletion of the cytoplasmic signalling domain of TF(TF§CT/§CT), deletion of PAR-2(PAR-2-/-) and combined deletion of TF signalling domain and PAR-2(TF§CT/§CT/PAR-2-/-). Hepatic fibrosis area was assessed by quantitative imaging of picrosirius red staining. Hepatic collagen content was assessed by hydroxyproline levels. Hepatic stellate cells(αSMA positive) and hepatic macrophages(CD68 positive) were identified by immunohistochemistry. Hepatic gene expression was determined by PCR and liver TGFβ1 content by ELISA.RESULTS CCl4 treated mice with deletion of the PAR-2 gene(PAR-2-/-) and the cytoplasmic domain of TF(TF§CT/§CT) developed significantly less hepatic fibrosis, characterised by reduced liver fibrosis area and hydroxyproline content, compared to control wildtype mice treated with CCl4. The observed reduction in histological fibrosis was accompanied by a significant decrease in the hepatic content of TGFβ, the prototypic fibrogenic cytokine, as well as fewer activated hepatic stellate cells and hepatic macrophages. Deletion of the TF cytoplasmic signalling domain reduced hepatic fibrosis to levels similar to thoseobserved in mice lacking PAR-2 signalling but combined deletion provided no added protection against fibrosis indicating a lack of mutual modulating effects that have been observed in other contexts such as angiogenic responses.CONCLUSION Tissue factor cytoplasmic domain is involved in TF-PAR-2 signalling initiating hepatic fibrosis and is a potential therapeutic target, as its deletion would not impact coagulation.Virginia Knight Dinushka Lourensz Jorge Tchongue Jeanne Correia Peter Tipping William Sievert 2017World Journal of Gastroenterology2017,23,31:3
