Abstract:
1. A light source device comprising: a light source section that supplies a laser beam; a wavelength conversion element that converts a wavelength of the laser beam from the light source section; a temperature measuring section that measures temperature; a temperature adjusting section that adjusts the temperature of the wavelength conversion element in accordance with a result of the measurement by the temperature measuring section; and a thermal diffusion section that diffuses heat to be conducted to the wavelength conversion element, wherein the thermal diffusion section is provided with a first surface disposed on a side of the wavelength conversion element and a second surface disposed on an opposite side to the first surface, and the temperature measuring section is provided to a part of the thermal diffusion section, which is located on a side of the second surface and has higher thermal conductivity of the thermal diffusion section between the side of the first surface and the side of the second surface than the other part of the thermal diffusion section.
