Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
In a fluid-filled laser generator cell: a. an elongated hollow body having first and second ends; b. means for imparting energy to a fluid to be contained within said body; c. .Iadd.non-closure .Iaddend.window means within said body at a position intermediate said ends, said window means being oriented with respect to the longitudinal axis of said body at an angle about equal to its Brewster angle; and d. closure means .Iadd.at .Iaddend.at least one of said ends in association with means for reflecting oriented about perpendicularly to said longitudinal axis.
