Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
160 words
An assembly for arranging optical components of a laser, comprising: (a) a plurality of support structures including at least a first and a second support structure each having an intermediate surface with indentations defining inner surfaces for supporting optical components to include at least a leans and a lasant material, said said inner surfaces of said intermediate surface exert radially compressive forces in an inward direction on said optical components to include said lens and said lasant material, said compressive forces being substantially uniform throughout said inner surfaces such that said optical components to include said lens and said lasant material are securely optical alignment with each other, said first support structure intermediate surface being substantially not in contact with said second support structure intermediate surface; and (b) interlocking means positioned on each of said intermediate surfaces for interlocking said first and second support structures, said first support structure interlocking means being attached to said second support structure interlocking means.
