1. A method for transmitting power fluxes through a partially absorbing optic, the method comprising:
forming a linear coolant flow path between one surface of an optic and an optically transparent window spaced apart from the one surface and parallel to the one surface of the optic;
generating a light beam at a primary wavelength through the window and through the optic, the light beam having a power flux sufficient to melt a material; and
cooling the optic by flowing an optically transparent cooling fluid through the coolant flow path, in direct contact with the optic, while the light beam is passing through the window, through the cooling fluid, and through the optic.
