| 英文摘要 | A light emitting device includes a solid-state laser. A pumping light source emits pumping light for pumping the solid laser medium. An automatic temperature controller includes a temperature control element which controls the working temperature of the pumping light source to a target working temperature, a temperature sensor which detects the working temperature of the pumping light source, and a temperature control circuit which controls the temperature control element on the basis of the temperature detected by the temperature sensor so that the working temperature converges on the target working temperature. An automatic light output controller includes a driver which supplies pumping energy to the pumping light source and a light output control circuit which increases and reduces the pumping energy supplied by the driver to the pumping light source according to a photo-detecting signal representing the light output of the solid-state laser so that a desired light output is obtained. A target working temperature setting unit changes the working temperature of the pumping light source with the light output fixed, and obtains an optimal working temperature at which the pumping energy is optimized on the basis of the relation between the pumping energy and the working temperature when the working temperature is changed with the light output fixed, and sets the target working temperature, to the optimal working temperature. |
