22 Mar 2007 LASER COMPONENTS is pleased to announce Holo-Or’s launch of their new range of Top-Hat beam-shapers optimised and designed for a 2940m laser, which they believe to be the world’s first Top-Hat for this wavelength. The beam shaper accepts a 4.0mm Gaussian beam and creates a 200µm diameter Top-Hat spot at an 80mm working distance. The substrate is an 11mm diameter Sapphire disk. A simulated beam shape of this spot is displayed in the figure.
Capabilities include design, manufacture and anti-reflection coatings for off-the-shelf and custom diffractive optical elements. Standard parts include beam splitters, beam shapers (Top-Hat), beam samplers, and many others, on fused silica, ZnSe, Sapphire, PMMA (plastic) and other materials. Specialities include designing and manufacturing elements for high power lasers with high efficiency.
