摘要	An apparatus for coupling radiation of individual laser diode emitters into a common optical fiber is disclosed. The radiation is collimated along fast axis and combined by using crossed pairs of flat mirrors. The combined beams are collimated by a common slow axis collimating lens. The laser diode emitters are disposed on both sides of an optical axis of the slow axis collimating lens such that the optical path lengths from the emitters to the slow axis collimating lens are equal.
其他摘要	公开了一种用于将各个激光二极管发射器的辐射耦合到公共光纤中的装置。辐射沿快轴准直，并通过使用交叉的平面镜对进行组合。组合光束由共同的慢轴准直透镜准直。激光二极管发射器设置在慢轴准直透镜的光轴的两侧，使得从发射器到慢轴准直透镜的光路长度相等。
主权项	A light source comprising: a plurality of planar emitters for emitting light, wherein an emission of each said emitter is characterized by a slow-axis divergence and a fast-axis divergence; a plurality of fast-axis collimating means, one per each emitter, for collimating the emission of each emitter into a fast-axis collimated beam, wherein said fast-axis collimated beam continues to diverge in a slow-axis divergence plane; a slow axis collimating means, disposed downstream of the fast-axis collimating means, for collimating the fast-axis collimated beams into a single collimated beam; and a plurality of redirecting means, for redirecting the fast-axis collimated beams, so as to couple said fast-axis collimated beams to the slow axis collimating means such that: the fast-axis collimated beams are substantially parallel to each other and to an optical axis of the slow axis collimating means, the slow-axis divergence planes of the fast-axis collimated beams are substantially parallel to each other, and optical path lengths from the planar emitters to the slow axis collimating means are substantially equal.
