| 英文摘要 | PURPOSE:To obtain the stabilized photo output as well as to extend the life of the titled device by a method wherein the driving current level is determined at the starting point of scanning in such a manner that the photo output intensity of a laser diode will be brought to a constant level, while the temperature of the diode is detected, and when the temperature became higher than the prescribed one, the device is cooled using an electron cooler. CONSTITUTION:A constant output driving circuit 1 is connected to an electron cooler 3, consisting of a Peltier element and a high heat conductive material 3 provided with a laser diode 2 and a heat sensitive element 4 on the surface, is placed in the cooler 3. Then, the output of the heatsensitive element 4 is sent to a temperature controlling circuit 6 through the intermediary of an amplifier 5, and a part of the output of the circuit is fed back to the cooler 3 by the microprocessor 7 which is connected to the temperature controlling circuit 6. Thus, the drivng current level is determined at the starting point of scanning so that the photo output intensity will be brought to a constant level, and when the temperature detected by the element 4 became higher than the prescribed temperature, the diode 2 is cooled by the cooler 3. |
