MULTI-WAVELENGTH LASER GENERATING APPARATUS AND METHOD BY USING MULTI INJECTION LOCKING LASER DIODE

摘要

PURPOSE: A multi-wave laser generator and a method thereof are provided to have a narrow line width, an even output, and a high SMSRSide Mode Suppression Ratio. CONSTITUTION: A multi-wave laser generator includes a first light source(100) emitting a voluntary emitting light for generating a multi-wave laser or emitting output light wave-controlled by receiving light and oscillating with a wave which the received light has; a second light source(200) receiving the voluntary emitting light from the first light source and emitting amplified reflection light by at least one part of the received voluntary emitting light; and a multiplexer(300) receiving light emitting from the first light source and the second light source and multiplexing the received light.
