A high brightness and high power fiber coupling laser module with single diode laser ( LD) was designed and fabricated. The wavelength of GaAs semiconductor laser is 975 nm and power is 10 W. The numerical aperture of the fiber is 0. 18 and the core diameter is 105μm. When the drive current is 10 A, 9. 37 W output power is obtained from the fiber, the coupling efficiency is 94. 3%, and the brightness is 1. 64 MW/(cm2·str).
