Paper Abstract

A state-of-the-art laser beam shaper zoom optical system has been developed. This optical device, efficiently converts a 532 nm single-mode Gaussian intensity profile into top hat lines of variable size with peak-to-valley non-uniformities of ≤±8%. This hybrid zoom system is capable of generating line lengths ranging between 0.16 mm to 1 mm, and line widths of up to 15 μm. The lines are of square-like shape in the long axis while they remain Gaussian in the short axis. The system was designed, fabricated, and tested using a laser with a nominal input Gaussian beam waist of 2.25 mm at the 1/e2 intensity points, and a nominal M2 of less than 1.1. Techniques associated with the system alignment during the optical assembly and system integration are discussed. The optical design and test results of the diffractive-optical system are also presented.
