Abstract: A system includes a master oscillator configured to generate a low-power optical beam. The system also includes a planar waveguide (PWG) amplifier configured to generate a high-power optical beam using the low-power optical beam. The PWG amplifier has a larger dimension in a slow-axis direction and a smaller dimension in a fast-axis direction. The system further includes at least one adaptive optic (AO) element configured to modify the low-power optical beam along the slow-axis direction and to modify the low-power optical beam along the fast-axis direction. In addition, the system includes a feedback loop configured to control the at least one AO element. The modification in the slow-axis direction can compensate for thermal-based distortions created by the PWG amplifier, and the modification in the fast-axis direction can compensate for optical misalignment associated with the master oscillator and the PWG amplifier.

Abstract: This disclosure provides planar waveguides with enhanced support and/or cooling. One or more endcaps could be disposed between coating/cladding layers at one or more ends of a core region, where the core region is doped with at least one active ion species and each endcap is not doped with any active ion species that creates substantial absorption at pump and signal wavelengths. A core region could include at least one crystal or crystalline material, and at least one cladding layer could include at least one glass. Different types of coolers could be disposed on or adjacent to different coating/cladding layers. Side claddings could be disposed on opposite sides of a planar waveguide, where the opposite sides represent longer sides of the waveguide. Endcaps and one or more coolers could be sealed to a housing, and coolant can flow through a substantially linear passageway along a length of the waveguide. One side of a planar waveguide could be uncooled.

Abstract: A system includes a master oscillator configured to generate a low-power optical beam. The system also includes a planar waveguide (PWG) amplifier configured to amplify the low-power beam into a high-power output optical beam, where the PWG amplifier has a larger dimension in an unguided direction and a smaller dimension in a transverse guided direction. The system further includes an adaptive optic configured to pre-distort the low-power optical beam substantially along a single dimension prior to injection of the low-power optical beam into the PWG amplifier in order to compensate for thermal-based distortions created by the PWG amplifier. The single dimension represents the unguided direction. In addition, the system includes a feedback loop configured to control the adaptive optic.
