查询词典 quartz

Zn-diffused high power 650 nm AlGaInP/GaInP material with compressively strained multi-quantum-well active layer was fabricated. The zinc diffusion was used on the material facet in a sealed quartz tube. Photoluminescence spectra shows 175 meV blue-shift in the Zn diffusion area, which is transparent for 650 nm laser emission.

利用石英闭管法对金属有机化学气相沉积外延生长的应变量子阱650 nm AlGaInP/GaInP材料进行选择区域扩Zn，使扩Zn区域的光致发光谱的峰值蓝移达175 meV，形成对650 nm波长激光器的高透腔面，有益于减少激光器腔面光吸收，增加了激光器退化的光学灾变损伤阈值。
