Abstract
A method comprising the steps of propagating an infrared laser pulse in air, self-focusing the laser pulse until the laser reaches a critical power density, wherein molecules in the air ionize and simultaneously absorb a plurality of infrared photons resulting in a clamping effect on the intensity of the pulse, wherein the laser pulse defocuses and plasma is created, causing a dynamical competition between the self-focusing of the laser pulse and the defocusing effect due to the created plasma, the laser pulse maintaining a small beam diameter and high peak intensity over large distances, creating a plasma column, repeating the above steps to create a plurality of plasma columns, creating a parallel linear array with the plurality of plasma columns, and using the array to deflect an incident energy.
