Embodiments of the present invention provide a system and method for shaping an annular focal spot pattern to allow for more efficient optical coupling to a small gauge optical fiber. An embodiment of the present invention can include an illumination source operable to transmit an optical beam along an optical path, an optical fiber, and a correcting element positioned in the optical path between the illumination source and the optical fiber, the correcting element configured to reshape the optical beam to increase an amount of light received by the optical fiber.
