摘要：
We represent a design of a 20 W, fiber-coupled diode laser module based on 26 single emitters at 520 nm.The module can produce more than 20 W output power from a standard fiber with core diameter of 400 m and numerical aperture(NA) of 0.22. To achieve a 20 W laser beam, the spatial beam combination and polarization beam combination by polarization beam splitter are used to combine output of 26 single emitters into a single beam,and then an aspheric lens is used to couple the combined beam into an optical fiber. The simulation shows that the total coupling efficiency is more than 95%.
