Abstract:
A semiconductor laser apparatus is provided which can vary an output wavelength of a light source. A semiconductor laser diode and one or more heat source devices arranged around the semiconductor laser diode are integrated on one substrate. The semiconductor laser diode is configured to be uniformly heated by the heat source device. An output wavelength of the semiconductor laser diode can be easily and quickly varied.
