Abstract
A device for coupling a laser diode emission to an optical fiber is provided. The device utilizes two opposed mirrors to redirect the divergent light beam of the laser diode to within the smaller numerical aperture or angle of acceptance of the optical fiber. The two opposed mirrors can be, for example, concave elliptical mirrors, a convex spherical and a concave spherical mirror, or a planar mirror and a concave spherical mirror. Each mirror has an aperture therein to allow passage of the initial laser diode beam or the redirected beam to the optical fiber.
