Abstract:
1. A system for treating a surface of a material, comprising: a continuous kiln, comprising: a laser positioned such that a laser beam emitted by the laser enters through the enclosure inlet wherein the zones comprise: a first zone located before exposure to the laser beam, wherein the temperature is less than the temperature of the surface of the material during contact with the laser beam, and less than the melting point of the material; a second zone located where exposure to the laser beam occurs; a third zone located after exposure to the laser beam; and a fourth zone located after the third zone, wherein the temperature declines between the third zone and the fourth zone at a controlled rate, and wherein the material has a top surface and side edges, and wherein the laser sweeps across the top surface of the material while the material moves through the kiln and is conveyed in a direction perpendicular to the direction of the emitted laser beam, the laser beam sweeping in a pendular motion over a fixed line as the material is conveyed through the kiln and, wherein the sweep of the laser beam surpasses the side edges of the material.
