Abstract: In this paper, a high brightness fiber-coupled module with a central wavelength of 520 nm is simulated and designed by ray-tracing software ZEMAX and then is experimentally implemented. Three 1-W continuous-wave green LD single emitters based on TO-9-package are successively collimated, spatially combined, and focused into an optical fiber with a core diameter of 50 mu m and a numerical aperture of 0.22. The final output power of 1.53 W is obtained, corresponding to an optical-optical conversion efficiency of 51% and an electro-optical conversion efficiency of 10%. The tolerances between the simulation and the experimental result are analyzed and explained.
