Abstract
A light source device includes a semiconductor laser that outputs laser light, a polarization rotator that rotates a polarization plane of the light, a polarization splitter that transmits and reflects the light in accordance with the polarization plane, and a fluorescent body that emits light by being excited by the laser light. The light source device controls an amount of the light that excites the fluorescent body by controlling a rotational angle of the polarization plane in the polarization rotator in a time-series fashion.
