| 英文摘要 | PURPOSE:To maintain the temperature of a heat sink constant and to control the input current of a semiconductor laser element in response to the variation in the laser light by providing a thermoelectric cooling element of a temperature control element under the sink when mounting the laser element for emitting lights in bidirections and a detector for detecting one light on the sink of a support. CONSTITUTION:When a photodetector 5 and a semiconductor laser element 1 are placed on a heat sink fin 13, a thermoelectric cooling element 12 of a temperature control element is interposed therebetween. Then, a copper heat sink 8 having uneven surface is mounted on the element 12 through an insulating layer 11 and a metal plate 10, the photodetector 5 having an insulating layer is mounted on the bottom of the recess and at the side of the element 1, and the element for emitting lights 3, 4 in bidirections is provided. In this structure, a power source 7 for the thermoelectric cooling element having an amplifier 6 and a control circuit is connected between the photodetector 5 and the element 12, thereby maintaining the temperature of the element 12 constant and simultaneously correcting the variation in the laser lights. |
