1. A system for making a plasma zone plate, the system comprising:
at least one laser configured to provide first and second laser beams;
at least one of: i) a nonlinear medium, ii) a supply configured to provide a nonlinear medium, and iii) a support configured to hold a nonlinear medium; and
one or more optical elements configured to direct said first and second laser beams along substantially collinear paths in the same direction to said nonlinear medium with the first laser beam having a first focal length and the second laser beam having a second focal length that is different from the first focal length so that the first and second laser beams interfere and form an interference pattern on the nonlinear medium, wherein the one or more optical elements includes a focusing mirror configured to focus the first laser beam to have the first focal length, wherein the focusing mirror includes an aperture configured so that the second laser beam is directed through the aperture;
wherein the interference pattern is configured to form a distribution of plasma from the nonlinear medium so as to produce a plasma zone plate that is configured to modify propagation of a third laser beam transmitted therethrough.
