Abstract

PURPOSE:To perform temperature control for the LD element, by utilizing the forward voltage of LD element related to the junction temperature of LD element. CONSTITUTION:When the switch. conduct 31 is closed, the LG element 26 is sufficiently contacted and oscillated, and when the contact 30 is closed, the power application is insufficienct for the oscillation due to the resistor 28. With the terminal voltage of element by the circuit 32, the junction temperature and the standard operating temperature are compared and the control signal is fed to the temperature control circuit 33. The circuit 33, in case of cooling, feeds power to the peltier element via the terminal plates 21 and 23. Thus, LD is cooled by Peltier effect. When heating LD, the direction of power application of the element 22 is inversed. Thus, the junction temperature of LD element actually can quickly be detected and the temperature control of LD can be made.
