Fiber Coupling of High Power Laser Diode Modular Combined by Wavelength Coupling

摘要

We have researched some technical method today for coupling the fiber and the single laser installed in series, then draw a conclusion that we utilize the difference in wavelength of every laser diode and using edge filter to couple different wavelength single laser diode’s output beam into single-fiber. This method made the coupling efficiency more than 80% in coupling the 2W output power laser diode whose wavelength are 940nm and 980nm into 200um fiber. At the same time the method made the power supply miniaturized and integrated in a whole, then got a minitype high power fiber coupling laser diode modular in practice.
