摘要	A compound laser system for generating beams of high brightness and high power density by constructive phase coherent combination of the beams generated by a number of individual sources of coherent radiation three subsystems: a diode laser subsystem which is the source of power for the system; a combiner subsystem which combines the output of the diode lasers; and, an optional delivery subsystem which may be needed to deliver the combined output to its desired destination for industrial or medical applications. The combiner subsystem may be implemented in its entirety as an Integrated Optical Combiner, a single component performing all the combiner subsystem's functions. A preferred embodiments of the combine subsystem employs optical fibers having shaped cores to provide efficient matching to the geometry of typical laser diodes. Each diode laser's output of a diode laser array is captured by a single optical fiber with a core whose cross-sectional shape is contoured so that major and minor axes of a laser diode's output shape are not larger than major and minor axes of a optical waveguide and whose numerical apertures are closely matched to the numerical apertures in the directions of corresponding axes. The waveguides are combined in a combiner subsystem into a single output source whose cross-sectional shape depends on the number and cross-sectional shape if the input ports. A delivery subsystem takes output from the combiner subsystem using a standard round or contoured optical fiber core, depending on the cross-section shape of the combiner subsystem's output.
其他摘要	一种复合激光系统，用于通过由多个单独的相干辐射源三个子系统产生的光束的相位相干组合产生高亮度和高功率密度的光束：二极管激光子系统，它是系统的电源;一个组合子系统，它结合了二极管激光器的输出;并且，可选的输送子系统可能需要将组合输出输送到其工业或医疗应用的期望目的地。组合器子系统可以整体实现为集成光学组合器，单个组件执行所有组合器子系统的功能。组合子系统的优选实施例采用具有成形芯的光纤以提供有效的匹配典型激光二极管的几何形状。二极管激光器阵列的每个二极管激光器的输出由单根光纤捕获，该光纤具有其横截面形状轮廓的芯，使得激光二极管的输出形状的长轴和短轴不大于光波导的长轴和短轴。并且其数值孔径与相应轴方向上的数值孔径紧密匹配。波导在组合器子系统中组合成单个输出源，其横截面形状取决于输入端口的数量和横截面形状。输送子系统使用标准的圆形或轮廓光纤芯从组合器子系统获取输出，具体取决于组合器子系统的横截面形状输出。
