A method of fabricating an optical material includes providing input materials having a material softening temperature, melting the input materials, and flowing the melted input materials into a laser inclusion mitigation system. The melted input materials comprise one or more inclusions. The method also includes irradiating the input materials using a laser beam, fragmenting the one or more inclusions in response to the irradiating, and reducing a temperature of the input materials to less than the material softening temperature. The method further includes forming an optical material and annealing the optical material.
