Abstract
Abstract This disclosure is directed to a system of prisms so arranged and related to each other that one may form a collinear composite output laser beam by superimposing several laser beams of the same polarization but with different frequencies.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
An optical system for combining at least two separate laser outputs to provide a single output in which the separate beams are collinear and superimposed upon each other which; comprises, a plurality of identical isosceles prisms in optical alignment and spaced from each other, a portion of said prisms mounted with their base down with the remainder mounted with their base up with the up and down bases being in parallel planes, a separate totally reflecting prism mounted between the first and second prisms of said plurality of identical prisms, said separate totally reflecting prism being positioned such that incident light will be totally internally reflected onto its adjacent prism then through the remainder of said prisms with the output thereof emerging at a point collinear and superimposed on the output of a radiation beam incident on the first identical prism and passing optically through the remainder of said identical prisms and emerging at the same point.
Claim 2
Dependent Claim
157 words
An optical system for combining at least two separate laser outputs to provide a single output in which the separate beams are collinear and superimposed upon each other which; comprises, a plurality of identical isosceles prisms in optical alignment and spaced from each other, a portion of said prisms mounted with their base down with the remainder mounted with their base up with the up and down bases being in parallel planes, a separate totally reflecting prism mounted between the first and second prisms of said plurality of identical prisms, said separate totally reflecting prism being positioned such that incident light will be totally internally reflected onto its adjacent prism then through the remainder of said prisms with the output thereof emerging at a point collinear and superimposed on the output of a radiation beam incident on the first identical prism and passing optically through the remainder of said identical prisms and emerging at the same point.
Claim 3
Dependent Claim
47 words
A system as claimed in claim 1; wherein, said plurality of identical isosceles prisms are four 60* prisms with the first and second 60* prism mounted with their bases reversed and the third and fourth 60* prisms are mirror images of said first and second 60* prisms.
Claim 4
Dependent Claim
28 words
A system as claimed in claim 2; wherein, said separate totally reflecting prism is a 45*-45*-90* prism positioned with its base adjacent one face of the first prism.
