Abstract
A powerful high-brightness laser pump modules is configured with a plurality of spaced laser diodes each generating a light beam at a pump wavelength, and respective groups of optical components guiding the light beams along parallel light paths. The groups of the optical components each include a lens assembly and a bending mirror configured to couple the beam light into an output fiber which is common to all groups of the optical component. At least one optical component of each group is provided with a dielectric layer capable of preventing propagation of a backreflected light toward laser diodes at a wavelength different from the pump wavelength.
