Abstract

This paper is directed at proposing a new technique for building high energy optical components that will permit the use of heat transfer techniques that will remove substantially more thermal load than is presently possible. This paper will describe the use of impingement and nucleate boiling heat transfer in concert with an optical component that is made up of optical cells. The optical component is made up of optical cells which will permit the designer to fabricate an optic of any size. The basic design of the cells and how they are fit together are shown in drawings and schematics. The optical cells may be figured and polished either as a unit or individually. Of particular value is the ability of changing out optical cells without having to disturb the rest of the optical component. The faceplate of the optical cell may be virtually whatever the designer wishes. Of particular interest would be the failure due to damage of a section of the optic. Instead of having to refigure and polish the whole component, one may only have to change out the optical cell(s) as required and replace with a new cell(s). Equations and curves are provided to show how the technique is accomplished and the resulting temperature gradients for various faceplate materials that may be used.
