Optical microcavities have attracted tremendous interest in both fundamental and applied research in the past few decades, thanks to their small footprint, easy integrability, and high quality factors. Using total internal reflection from a dielectric int
A compact all-solid-state continuous-wave (CW) laser at 1047 nm is developed based on Nd:LuLF, which is grown through the Czochralski technique. From the laser system, 1.3-W laser can be obtained, which corresponds to the slope efficiencies of 20.1% and 4
本文分析了具有不同行波系数α的声光光学双稳特性,研究了声场状态对双稳特性的影响,进而指出,仅当声场具有一定的α值时,声光光学双稳态才有实际用途,如果α=1,即纯驻波情况下声光双稳性则失去了意义。实验与理论相符。
半导体激光器具有输出波长范围广、结构简单和易于集成等优势,广泛应用于医疗、传感、光学通讯、军事和航空航天等领域。随着应用需求不断增大,输出光功率不断提高,对激光器的可靠性提出了严峻的挑战。在回顾半导体激光器失效机理的基础上,分析光致发光技术、电致发光技术、阴极发光技术、红外热成像和微光显微镜5种有效的失效检测和分析手段,重点对有源区内部问题、腔面问题、焊接问题和操作环境问题的改善措施进行回顾和建议,为从事半导体激光器研究和生产的人员提供半导体激光器失效分析的依据。
