摘要：

In order to develop a wavelengths ultiplexing fiber-coupled module of high output power and high power denisty on the basis of single emitter semiconductor laser diode, and design a kind of new pump laser for fiber laser, a new-type fiber-coupled module composed of 30 LDs was designed based on ZEMAX optical design software, which can output three kinds of wavelengths. After collimation by micro lens, including FACs and SACs, spatial multiplexing, wavelength multiplexing, diversion by special mirrors, focusing by focus lens and coupling to a fiber, the module can produce above 357.91 W output power from a standard fiber with core diameter of 105 μm and numerical aperture (NA) of 0.22. The total fiber coupling efficiency is about 99.42%, and the power density is 27.24 MW/cm2. To test the practical feasibility of the module, analyzed the influence from the angle between the incident beam and the normals of optical fiber end face on the coupling efficiency, the results showed the effects from the angle is so tiny that can be neglected. At the same time, the application of ANSYS software for the thermal analysis of this module shows that the cooling performance of the module is pretty good. Therefore this module's performance is positive and of high reliability, which can meet the demand of single emitter semiconductor laser fiber-coupled module which is of high power, high brightness and multiple wavelengths. Additionally, this design is of great guiding significance for practical production. © 2018, Science Press. All right reserved.
