Abstract:

With the development of single emitter diode laser fiber coupling technology, in order to improve the output power of the multi-single emitters diode laser, the curved surface spatial combination, as a special way, was introduced to coupling the multi-single diode laser emitters into the fiber, which can combine the most number of single emitters in same optical fiber for increasing the output power. In simulation, with ZEMAX optical design software, 34 single emitters diode lasers with a center wavelength of 975 nm and 10 W output power are coupled into a fiber with core diameter of 200 μm and NA of 0.22. The simulation results of the maximum output power of 312.03 W and the coupling efficiency of 91.76% were obtained. We assembled a multiple single emitter diode laser based on 17 single emitters and coupled the beam into the optical fiber of which the core diameter is 200 μm and the numerical aperture is 0.22. Under 10.5 A driving current, the output power is 100.5 W and the coupling efficiency to be 68.46%. © 2018, Science Press. All right reserved.
