Abstract
An external resonator-type laser having a narrow line width according to the present disclosure includes a gain chip having a laser gain, a lens for collimating light emitted from the gain chip into parallel light, and a wavelength selective filter for transmitting light having a specific wavelength among the light collimated through the lens, wherein two-sided heat transfer members disposed on at least one side of at least one of the lens and the wavelength selective filter and made of a material having a higher heat transfer rate than the lens and the wavelength selective filter, are included.
