Abstract
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.Keywords
