Abstract:
A multi-layer laser resistant structure comprising:a generally opaque outer layer;an intermediate layer of ethylene glycol;an inner layer;means for maintaining said inner and outer layers a generally fixed distance apart to form a space for containing said liquid;means for hermetically sealing the space between said inner and outer layers;hydraulic tubing coupled to said space, said tubing forming a generally circuitous conduit with said cell;a reservoir of said liquid connected to said hydraulic tubing;circulating pump means connected to said tubing; anda heat exchanger connected to said tubing,such that said liquid will be circulated by said pump in said space to absorb heat generated in said outer layer by laser radiation incident thereon, said heat exchanger extracting heat transferred to said liquid to significantly mitigate effects of incident laser radiation on said outer layer.
