<p>A laser systemt(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.</p> |
