将一种新型窗口结构--端面生长窗口（WGF）应用于780 nm波长的10%-95%镀膜窄条激光器。通过优化窄条结构，在不降低微分量子效率的情况下，获得光束发散的纵横比为2。在70 mW CW和60°C下可实现4000小时以上的高可靠性运行。
A novel window structure referred to as window grown on facets (WGF) is applied to a 10%-95% coated narrow-stripe laser with a wavelength of 780 nm. An aspect ratio of 2 in the beam divergence without a decrease in the differential quantum efficiency is obtained by optimizing the narrow-stripe structure. Highly reliable operation under 70 mW CW at 60°C is attained beyond 4000 hours.
