中文摘要：

横梁联合和联合纤维的模块的联合效率由于常规半导体激光二极管的大垂直分叉的角度被限制。我们在场用 photonic-band-crystal (PBC ) 的一个高联合效率模块有狭窄的垂直分叉的角度的激光二极管。三根 PBC 单个发射极的激光二极管与 105 m 和 0.22 的数字孔的核心直径被相结合进纤维。高联合 94.4% 的效率的 A 被完成，亮度是打算的与 8 A 的注射水流是 1.7 MW/(cmsr ) 。

英文摘要：

The coupling efficiency of the beam combination and the fiber-coupled module is limited due to the large vertical divergent angle of conventional semiconductor laser diodes. We present a high coupling efficiency module using photonic-band-crystal （PBC） laser diodes with narrow vertical divergent angles. Three PBC single-emitter laser diodes are combined into a fiber with core diameter of 105μm and numerical aperture of 0.22. A high coupling efficiency of 94.4% is achieved and the brightness is calculated to be 1.T MW/（cm2.sr） with the injection current of 8A.
