Extended focus diffractive optical element for Gaussian laser beams

Not Accessible

Your library or personal account may give you access

Abstract

The depth of focus of the Gaussian beam is extended by introducing a wavefront phase correction with properly designed diffractive optical elements. Results of the computer simulations show that, compared with other methods, the presented method demonstrates a reduced focal spot size and low sidelobes in a focal domain, within a considerable range of defocusing distances. Experimental results for the visible range diffractive optical element with a focus of 40mm and a depth of focus that extends to 1mm agree with the theory.
