Abstract

A light source apparatus (100) includes a light emitting element (101) configured to emit first light, a wavelength conversion element (105) configured to convert part of first light into second light having a wavelength different from that of the first light, and to emit the second light and unconverted light that is the first light which is not converted into the second light, and an optical element (103) configured to cause the first light from the light emitting element to enter the wavelength conversion element, and the second light and the unconverted light from the wavelength conversion element to travel in a direction different from a direction of the light emitting element. The wavelength conversion element emits the second light and the unconverted light as linear polarization light.
