摘要	The invention relates to bi-directional long-cavity semiconductor lasers for high power applications having two AR coated facets (2AR) to provide an un-folded cavity with enhanced output power. The lasers exhibit more uniform photon and carrier density distributions along the cavity than conventional uni-directional high-power lasers, enabling longer lasers with greater output power and lasing efficiency due to reduced longitudinal hole burning. Optical sources are further provided wherein radiation from both facets of several 2AR lasers that are disposed at vertically offset levels is combined into a single composite beam.
其他摘要	本发明涉及用于高功率应用的双向长腔半导体激光器，其具有两个AR涂层小平面（2AR），以提供具有增强输出功率的未折叠腔。与传统的单向高功率激光器相比，激光器沿腔体显示出更均匀的光子和载流子密度分布，使得更长的激光器具有更大的输出功率和激光效率，因为减少了纵向孔烧损。还提供了光源，其中来自设置在垂直偏移水平的几个2AR激光器的两个面的辐射被组合成单个复合光束。
主权项	A long-cavity semiconductor laser device (SLD) for high-power applications, comprising:a semiconductor laser chip comprising: first and second facets defining a laser cavity therebetween, and a laser waveguide extending between the first and second facets and comprising an active layer for generating laser light; wherein the laser cavity is at least 5 mm long, and wherein each of the first and second facets comprises anti-reflection coating that is configured for reflecting back into the laser cavity between 0.1% and 10% of the laser light incident upon the respective facet, and for outputting at least 90% of the laser light incident thereupon.
