1. A method of direct write fabrication of a structure on a substrate, the method comprising: recording a holographic pattern into a holographic lens;  generating a photonic lens by focusing a light beam through said holographic pattern on said holographic lens, whereby said holographic pattern diffract, said light beam to cause formation of geometrically stable holographic light fields and thereby establish said photonic lens; and  passing a particle beam through said photonic lens, wherein Lorenz field interactions between particles of said particle beam and said holographic light fields of said photonic lens affect a direction of movement of a multiplicity of said particles and whereby a portion of said multiplicity of particles are focused towards a structure construction site located on the substrate.  mathematically modeling the structure to be built on the substrate;  selecting particles that will be used to construct the structure;  determining a vector, energy state and pathway of said particle beam at the time said particle beam passes through said photonic lens;  back calculating a holographic pattern of said photonic lens that will direct, by means of Lorenz force interaction, said particles of said particle beam to form the structure on the substrate;  back calculating at least one laser frequency required to generate said photonic lens;  back calculating at least one holographic pattern of said holographic lens required to generate said photonic lens;  writing at least one back calculated holographic pattern into said holographic lens; and  positioning said holographic lens and at least one laser source in relationship to the substrate and said particle beam whereby said photonic lens is formed in proper orientation to said particle beam and the substrate in order to direct said particle beam to build the structure.  forming a grazing incidence nozzle, said nozzle comprising an internal surface, a wide intake orifice and a narrow outflow aperture; and  directing said particle beam through said intake orifice and towards said outflow aperture, whereby some of the individual particles of the particle beam ballistically strike said internal surface and the trajectories of said particles are thereby modified to increase the degree of collimation of said particle beam. 2. The method of claim 1 wherein said particle beam comprises a substantively homogeneous stream of atoms. 3. The method of claim 1 wherein said particle beam comprises a substantively homogeneous stream of molecules. 4. The method of claim 1 wherein said particle beam comprises a substantively isotopically homogeneous stream of atoms. 5. The method of claim 1 wherein said particle beam comprises a substantively isotopically homogeneous stream of molecules. 6. The method of claim 1 wherein said particle beam substantively comprises atoms of a particular elemental isotope. 7. The method of claim 1 wherein said particle beam substantively comprises molecules of a particular molecular isotope. 8. The method of claim 1, further comprising the steps of: 9. The method of claim 8 wherein said particle is an isotopically specific atom. 10. The method of claim 8 wherein said particle is an isotopically specific molecule. 11. The method of claim 1, further comprising collimating said particle beam by: 12. The method of claim 11, further comprising the step of generating evanescent waves proximate to said internal surface of said grazing incidence nozzle, whereby said evanescent waves act as a particle mirror and repel said individual particles away from said internal surface and contamination of said internal surface is thereby reduced. 13. The method of claim 12, wherein said evanescent waves are formed by passing at least two laser beams through at least one thin dielectric layer located proximate to said internal surface. 14. The method of claim 11 wherein said particle is an isotopically specific atom. 15. The method of claim 11 wherein said particle is an isotopically specific molecule. 16. The method of claim 11 further comprising passing the collimated particle beam from said outflow aperture of said grazing incidence nozzle through an optical molasses region prior to passing said particle beam through said photonic lens. 17. The method of claim 16 further comprising passing the particle beam from said optical molasses region through an output coupler comprising a pair of tuned traveling/evanescent wave plates prior to passing said particle beam through said photonic lens. 18. The method of claim 1 further comprising passing said particle beam through an optical molasses region prior to passing said particle beam through said photonic lens. 19. The method of claim 1 further comprising passing said particle beam through an output coupler comprising a pair of tuned traveling/evanescent wave plates prior to passing said particle beam through said photonic lens.
