A surface laser diode package having an optical power monitoring function for a surface laser beam has a surface laser diode for making a spontaneous emission beam generated from an active region oscillate by means of an upper mirror and a lower mirror, and emitting a surface laser beam obtained by the oscillation. A monitor diode, installed between a substrate and the lower mirror of the surface laser diode, performs a light detection operation with respect to the surface laser beam emitted toward the substrate via the lower mirror, in order to monitor the optical power of the surface laser diode.
