| 英文摘要 | A problem of the present invention is to provide a semiconductor laser module for making precise temperature control possible. A semiconductor laser module 1 according to the present invention has a Peltier element 4, a thermistor 5 for detecting the temperature of the Peltier element 4, and a differential amplification circuit 6 for generating a control signal according to the detection signal from the thermistor 5 so that the surface temperature of the Peltier element 4 conforms to a set temperature. A parallel compensating circuit 12 for generating a compensating signal for compensating for a delay in temperature variation in the Peltier element 4 with respect to the input of current signal to the Peltier element 4 branches and is connected to the output portion of the differential amplification circuit 6. The compensating signal is sent to an addition circuit 9 and detection correction signal obtained by adding the detection signal of the thermistor 5 and the compensating signal is generated. The detection correction signal is sent to the differential amplification circuit 6 and a control signal corresponding to the difference between the detection correction signal and a signal corresponding to set temperature is generated. |
