HIGH-POWER LASER DIODE MODULE HAVING MULTI-LAYER STRUCTURE

摘要

The present invention relates to a high-power laser diode module having a multi-layer structure, each comprising a first base and a second base formed in a two-layer stepped structure through a stepped arrangement of steps, and a second base positioned opposite to each other so as to be symmetrical to each other on a substrate a laser providing unit in which a plurality of laser diodes each outputting a laser beam in a direction opposite to each other are disposed on the first and second proximal ends in a step shape having a step difference in the longitudinal direction; a laser transmission unit located at the same height as the laser providing unit and converting the vertical and horizontal laser beams provided from the laser providing unit into a parallel light form and reflecting the converted laser beam into a parallel light form; and a laser focusing unit converging a plurality of laser beams output from the laser providing unit; installed in the first and second layer portions of the multilayer plate structure, respectively, and incident to the laser focusing unit from the first and second layer portions Provided is a high-power laser diode module having a multi-layer structure including a focusing lens installed in the first layer part and focusing to condense a plurality of laser beams to be incident on an optical fiber.
