Abstract
A light source device includes a laser element, a temperature sensor adapted to measure the temperature of the laser element, and a control device adapted to control a value of a current supplied to the laser element based on the measurement value obtained by the temperature sensor. Assuming that a maximum value of an output of a laser beam which the laser element can emit without being damaged is a maximum output, the control device controls the current value in accordance with the measurement value so that the output of the laser element does not exceed the maximum output.
