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

3外阴癌:流行病学与发病机理显示文摘外阴癌是一种罕见疾病,发病率约为1.8/10万。外阴癌的临床和流行病学研究已集中于种族团体中流行的类型。已发现与外阴癌有关的重要危险因素是有其他的生殖系癌瘤、慢性外阴炎、外阴癌前病变(外阴上皮内肿瘤,VIN)、吸烟及生殖疣病史。人乳头状瘤病毒正在探索(HPVs)在外阴癌的发生中直接起作用的可能性。现有调查资料可提出一种假说:外阴癌至少含有二种或更多的亚型。Crum CP 宿爱琴 1993国外医学(妇产科学分册)1993,20,1:2
