Abstract: A method is provided for operating one or more one solid-state electro-optic device to provide an electrically switching shutter. The method includes forming an alternating stack of first semiconductor layers having a first dopant and second semiconductor layers having a second dopant to form at least one superlattice semiconductor device. The method further includes applying to the at least one superlattice semiconductor device a first voltage to induce a transparent state of the alternating stack such that light is transmitted through the alternating stack, and applying to the at least one superlattice semiconductor device a second voltage different from the first voltage to induce an opaque state of the alternating stack such that light is inhibited from passing through the alternating stack.

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 threaded cooling apparatus includes a head having a heat exchanger and a shaft having a threaded section configured to mechanically fasten the head to a structure. The heat exchanger is configured to exchange heat with a coolant flowing through the head. The shaft also includes first and second cooling channels. The first cooling channel is configured to deliver the coolant to the heat exchanger, and the second cooling channel is configured to exhaust the coolant from the heat exchanger. The apparatus may also include a first seal between the head and the structure that is configured to reduce or prevent coolant loss. The apparatus may further include a second seal that is configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger.

Abstract: A system includes a master oscillator configured to generate a low-power optical beam. The system also includes a planar waveguide (PWG) amplifier having one or more laser diode pump arrays, a planar waveguide, and a light pipe. The one or more laser diode pump arrays are configured to generate pumplight. The planar waveguide is configured to generate a high-power optical beam using the low-power optical beam and the pumplight. The light pipe is configured to substantially homogenize the pumplight and to inject the homogenized pumplight into the planar waveguide. The light pipe is also configured to inject the low-power optical beam into the planar waveguide.
