HIGH POWER LASER DIODE MODULE WITH A RELIABLE SINGLE WAVELENGTH WHICH IS THERMALLY AND ELECTRICALLY STABLE AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A high power laser diode module and a manufacturing method thereof are provided to use two single laser diode chips, thereby combining two times of power with a single optical fiber.;CONSTITUTION: A first laser diode chip(100) and a second laser diode chip(200) project a laser beam of a single wavelength by generating a monochromatic laser beam. The first and second laser diode chips are welded to be facing each other in order to electrically be connected to an electrode of the same polarity. The electrode of the same polarity is electrically connected to an external conductor. A first and second sub mounts(300,400) are respectively welded on an exposed surface facing with the welded surface of the first and second laser diode chips. The first and second sub mounts emit heat generated in a laser light emission driving state.;COPYRIGHT KIPO 2012
