摘要： A low numerical aperture fiber output diode laser module, which having several independent diode lasers, and collimated and converged the light beam, for the coupling the light to the core optical fiber with a core diameter of 105 um and a numerical aperture of 0.12. Compared with general products with a numerical aperture of 0.22, the light output angle is reduced to 55%, and use a general blue laser diode for verification. Use an optical software for facilitating the design and optimization of the parameters of the optical lens module.
