A laser system 1 is composed of a temperature control section 12 that has a Peltier device 9 , a heat sink 10 , and a base plate 11 ; and a laser section 8 that has a laser diode 2 , a lens 3 , a grating 5 , a first support member 5 , and second support member 6 . The heat sink 10 is connected to the base plate 11 and is perpendicular thereto. The Peltier device 9 is connected to the heat sink 10 . The second support member 6 of the laser section 8 is connected to the Peltier device 9 so that one surface of the Peltier device 9 is connected to the heat sink 10 and the other surface of the Peltier device 9 is connected to the second support member 6 . Heat generated in the laser diode 2 , the lens 3 , the first support member 5 , and so forth, which compose an external cavity type semiconductor laser, is transmitted through the second support member 6 , the Peltier device 9 , the heat sink 10 , and the base plate 11 . When the distance by which the base plate 11 and the laser section 8 are spaced apart is a predetermined value or more, heat transmitted to the laser section 8 can be effectively blocked.
