Abstract

The invention discloses a large-aperture optical element whole-perimeter cooling device which comprises an upper cover plate, a lower cover plate, a water inlet pipe and a water outlet pipe. The upper cover plate is mounted above the lower cover plate. The lower surface of the upper cover plate and the upper surface of the lower cover plate are provided with cooling water channel grooves which correspond with each other and have annular openings. Two ends of each cooling water channel groove are respectively provided with a water inlet and a water outlet. The water inlet and the water outlet are respectively connected with the water inlet pipe and the water outlet pipe. Water cooling is performed on the large-aperture optical element through the large-aperture optical element whole-perimeter cooling device. Detachment of the large-aperture optical element is not required. Just through introducing cooling water into the cooling water channel grooves and making the water flow in the cooling water channel grooves, heat of the large-aperture optical element can be taken away, thereby realizing online cooling for the large-aperture optical element.

Description

technical field [0001] The invention relates to a cooling device for an optical element, in particular to a cooling device for the entire circumference of a large-diameter optical element. Background technique [0002] Large-aperture optical components used in inertial confinement fusion devices undertake the task of frequency conversion of high-energy lasers. When the high-energy laser propagates inside the large-aperture optical element, the large-aperture optical element absorbs part of the energy of the high-energy laser and converts it into its own heat energy, causing its own temperature to rise, which will lead to a decrease in frequency conversion efficiency. Installing a suitable cooling device to the optical element holding assembly can cool the large-aperture optical element online, which is beneficial to improve the frequency conversion efficiency. However, the existing cooling devices for large-aperture optical components cannot achieve online cooling, and the ...
