Abstract
Abstract The invention disclosed in this application provides a unique cladding structure for holding laser disc elements structurally rigidly aligned and allows for release of stress produced by heating of the disc element. One unique material for this is ''''FEP'''' Teflon which is a Copolymer of Hexafluoropropylene and Tetrafluoroethylene in conjunction with ruby.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
17 words
The device of claim 1 wherein said plastic cladding material is a Copolymer of Hexafluoropropylene and Tetrafluoroethylene.
Claim 2
Dependent Claim
24 words
The device of claim 2 wherein said lasable elements are substantially disc shaped having a diameter substantially larger than the thickness of said disc.
Claim 3
Dependent Claim
50 words
The device of claim 3 wherein portions of said cladding material have a length greater than said thickness of said lasable element to provide spacing between said elements when aligned in said assembly along said axis for allowing the flow of a cooling liquid past the faces of said elements.
Claim 4
Dependent Claim
59 words
The device of claim 4 wherein a portion of said cladding material is removed about the outer circumference of said cladding material to allow for passage of cooling fluid past one face of the lasable element to the other face of said lasable element to provide a series type flow of said cooling liquid past the individual lasable elements.
Claim 5
Dependent Claim
32 words
The device of claim 5 wherein the protion of removed circumference of said cladding material is at least a chord subtended by an angle equal to the diameter of said disc element.
Claim 6
Dependent Claim
47 words
The device of claim 6 wherein the portion of the cladding to provide spacing between elements consists of two substantially equal parts at opposite sides of said element and defined therebetween a channel to allow cooling liquid to flow past the entire face of said disc elements.
Claim 7
Dependent Claim
50 words
The device of claim 7 wherein alternate ones of said lasable elements have cladding removed from a portion of the circumference of said cladding and the removed portion is substantially 180* from adjacent elements so that coolant liquid flow is in a series arrangement past faces of said lasable elements.
