  • Patent number: 10495958
    Abstract: A cooling device of an optical element includes a circulation passage through which a fluid circulates. The circulation passage includes a window portion that is disposed on an incidence side or an emission side of the optical element and transmits light, an evaporation portion that is connected to the window portion and includes a plurality of channel portions, and a heat radiation portion that radiates heat of the fluid. The fluid transmits the light in a liquid state. The fluid is a liquid in the window portion. The fluid that is a liquid evaporates to vapor in the plurality of channel portions. The fluid that is vapor condenses into a liquid in the heat radiation portion. A sectional area of each channel portion is less than a sectional area of a boundary between the window portion and the evaporation portion.
