Abstract
In a high power optical system, a thermal waveguide including an optical material having an index of refraction sensitive to changes in temperature, the rectangular optical material having a first dimension and a second dimension in a horizontal plane and a third dimension in a vertical plane, the third dimension being approximately ten times smaller than the first and second dimension, at least one heat sink thermally coupled to the optical material to establish a one-dimensional thermal gradient across the third dimension of the optical material, the thermal gradient having a parabolic profile across the rectangular optical material, and wherein the optical material is configured to act as a waveguide when a laser beam having a power of greater than one watt is incident upon the optical material.
