Optical module, optical fiber laser device and image display device

摘要

The fast-axis and slow-axis direction components of light exited from any light emitting sections are respectively independently collimated to allow the light beams which are collimated in both the fast-axis and slow-axis directions to be shaped and/or image-converted to a predetermined cross-sectional configuration at least relative to the slow-axis direction components and allow the light beams which are given the predetermined cross-sectional configuration to be condensed to a predetermined position. By doing so it is possible to reduce any loss involved upon the optical coupling of a laser array to an optical fiber.
