1High efficiency, high power 808nm laser array and stacked arrays optimized for elevated temperature operation显示文摘Operation of 808-nm laser diode pumping at elevated temperature is crucial to many applications. Reliable operation at high power is limited by high thermal load and low catastrophic optical mirror damage (COMD) threshold at elevated temperature range. We demonstrated high efficiency and high power operation at elevated temperature with high COMD power. These results were achieved through device design optimization such as growth conditions, doping profile, and materials composition of the quantum-well and other layers. Electrical-to-optical efficiency as high as 62% was obtained through lowered threshold current, lowered series resistance and increased slope efficiency. The performance of single broad-area laser diodes scales to that of high power single bars on water-cooled copper micro-channel heatsinks or conductively-cooled CS heatsinks. No reduction in bar performance or significant spectral broadening is seen when these micro-channel coolers are assembled into 6-bar and 18-bar CW stacks for the highest power levels.Crump P A Crum T R DeVito M Farmer J Grimshaw M Huang Z Igl S A Macomber S Thiagarajan P Wise D 2004光机电信息2004,21,6:4

3The impact of pastoralist mobility on tuberculosis control in Ethiopia:a systematic review and meta-synthesis显示文摘Background:Directly observed treatment,short-course(DOTS)is the current mainstay to control tuberculosis(TB)worldwide.Context-specific adaptations of DOTS have impending implications in the fight against TB.In Ethiopia,there is a national TB control programme with the goal to eliminate TB,but uneven distribution across lifestyle gradients remains a challenge.Notably,the mobile pastoralist communities in the country are disproportionately left uncovered.The aim of this study was to summarize the evidence base from published literature to guide TB control strategy for mobile pastoralist communities in Ethiopia.Main text:We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines and systematically reviewed articles in seven electronic databases:Excerptra Medical Database,African Journal Online,PubMed,Google Scholar,Centre for Agriculture and Bioscience International Direct,Cochrane Library and Web of Science.The databases were searched from inception to December 31,2018,with no language restriction.We screened 692 items of which 19 met our inclusion criteria.Using a meta-ethnographic method,we identified six themes:(i)pastoralism in Ethiopia;(ii)pastoralists’livelihood profile;(iii)pastoralists’service utilisation;(iv)pastoralists’knowledge and awareness on TB control services;(v)challenges of TB control in pastoral settings;and(vi)equity disparities affecting pastoralists.Our interpretation triangulates the results across all included studies and shows that TB control activities observed in pastoralist regions of Ethiopia are far fewer than elsewhere in the country.Conclusions:This systematic review and meta-synthesis shows that TB control in Ethiopia does not align well with the pastoralist lifestyle.Inaccessibility and lack of acceptability of TB care are the key bottlenecks to pastoralist TB service provision.Targeting these two parameters holds promise to enhance effectiveness of an intervention.Faisal Nooh Lisa Crump Abdiwahab Hashi Rea Tschopp Esther Schelling Klaus Reither Jan Hattendorf Seid M.Ali Brigit Obrist Jurg Utzinger Jakob Zinsstag 2019Infectious Diseases of Poverty2019,8,5:2
