摘要： A light source apparatus includes a light source unit that supplies light having a first wavelength, a wavelength conversion element that converts the light having the first wavelength into the light having a second wavelength different from the first wavelength, and a wavelength separator that separates the first-wavelength light from the second-wavelength light. The wavelength separator directs the second-wavelength light from the wavelength conversion element in the exit direction and the first-wavelength light from the wavelength conversion element in a direction other than the exit direction.

Due to the foregoing, a highly reliable blower used for a laser oscillator, the reduction of the blower efficiency of which is suppressed to be as small as possible, can be provided.
