Cooling system for high powered light beam in optics
A recently granted patent (Publication Number: US11999106B2) discloses a method for transmitting power fluxes through a partially absorbing optic using a unique cooling system. The method involves forming a linear coolant flow path between the optic and an optically transparent window, generating a light beam with sufficient power flux to melt a material, and cooling the optic by flowing an optically transparent cooling fluid through the coolant flow path while the light beam passes through the optic. Additional features include using multiple coolant flow paths, a heat exchanger to remove heat from the cooling fluid, and a closed-loop coolant flow system. The method also involves generating light beams at different wavelengths and utilizing a laser to achieve the desired power flux.
Furthermore, the patent describes a method for transmitting power fluxes high enough for additive manufacturing using an optic with opposing surfaces, coolant flow paths along these surfaces, and a cooling system with optically transparent cooling fluid. The method involves generating a light beam with sufficient power flux to melt material for additive manufacturing, cooling the optic by flowing the cooling fluid through the coolant flow paths, and utilizing a closed-loop circuit for efficient cooling. The use of a laser with specific wavelength characteristics and the transparent-absorptive properties of the optic are highlighted in the patent claims. Overall, the patented method offers a novel approach to transmitting power fluxes through optics for various applications, including additive manufacturing.
