The purpose of the experimental and theoretical research proposed here          is to design and study amplitude transmission apertures that create and         transmit beams not subject to diffraction spreading.  The technical and         theoretical feasibility of non-diffracting apertures was proposed               recently in theoretical work at the University of Rochester by Durnin.          Professor Eberly proposes to demonstrate the formation and propagation          of optical beams with spot sizes smaller than 100 microns with less             than 10% beam spreading over path lengths on the order of meters.  The          potential is great for near-term applications in such areas as                  laser-scribing, laser micro-welding and even laser surgery, where               narrowly focused beams with unusual depth of field are desirable.
