Laser module and temperature regulation method thereof

Abstract

The present invention relates to a laser module and a temperature regulation method thereof. The laser module of a modulation light source and an optical part comprises a light source emitting laser; an optical part arranged in a light path of the laser emitted from the light source; a substrate installed at one side surface of the light source and the optical part; a housing storing the substrate; a temperature regulation device arranged between the other side surface of the substrate and the inner surface of the housing with respect to the other side surface, contacted with the substrate and configured to adjust the temperature of the substrate; and an insulation component arranged between the side surface and the inner surface of the housing.
