Abstract: A method for generating a frequency converted pulse includes providing a first pulse at a fundamental wavelength propagating in a first beamline and providing a second pulse at the fundamental wavelength propagating in a second beamline. The method also includes frequency converting the first pulse at the fundamental wavelength to provide a first frequency converted pulse at a frequency converted wavelength and frequency converting the second pulse at the fundamental wavelength to provide a second frequency converted pulse at the frequency converted wavelength. The method further includes optically combining the first frequency converted pulse at the frequency converted wavelength and the second frequency converted pulse at the frequency converted wavelength to provide the frequency converted pulse.

Abstract: 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 onto 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.

Abstract: An optical gain architecture includes a pump source and a pump aperture. The architecture also includes a gain region including a gain element operable to amplify light at a laser wavelength. The gain region is characterized by a first side intersecting an optical path, a second side opposing the first side, a third side adjacent the first and second sides, and a fourth side opposing the third side. The architecture further includes a dichroic section disposed between the pump aperture and the first side of the gain region. The dichroic section is characterized by low reflectance at a pump wavelength and high reflectance at the laser wavelength. The architecture additionally includes a first cladding section proximate to the third side of the gain region and a second cladding section proximate to the fourth side of the gain region.
