A green optical module is provided to secure optimized thermal stability by combining the material quality and the thickness of a heat sink corresponding to a laser light source and a harmonic generator at need. A green optical module(100) includes a harmonic generator(130), a laser light source(110), and heat sinks(141,142). The harmonic generator(130) generates a second harmonic. The laser light source(110) generates light to pump the harmonic generator(130). More than two heat sinks(141,142) are separated each other. The harmonic generator(130) and the laser light source(110) are installed on a top surface of each heat sink(141,142). The green optical module(100) further includes a thermoelectric cooling device(120). The heat sinks(141,142) are installed on a top surface of the thermoelectric cooling device(120) to be mutually separated at predetermined intervals.
