摘要	An apparatus includes a PWG amplifier (104) having a core region (210) and a cladding layer (212). The amplifier is configured to receive pump light (204). The core region is configured to amplify an input beam (202) using energy from the pump light to generate an amplified output beam. The apparatus also includes a cooling fluid (214) configured to cool the core region. The cooling fluid has a lower refractive index than the core region and the cladding layer in order to support guiding of the input beam and pump light within the amplifier. The amplifier also includes first and second endcaps (206, 208) attached to opposite faces of the core region and cladding layer. The core region, cladding layer, and endcaps collectively form a monolithic fused structure. Each endcap has a major outer surface that is larger in area than a combined area of the faces of the core region and cladding layer to which the endcap is attached.
其他摘要	一种装置包括PWG放大器（104），其具有芯区（210）和包层（212）。放大器配置为接收泵浦光（204）。核心区域被配置为使用来自泵浦光的能量放大输入光束（202）以产生放大的输出光束。该装置还包括冷却流体（214），其配置成冷却核心区域。冷却流体具有比芯区域和包层低的折射率，以便支持输入光束的引导和泵浦光在放大器内。放大器还包括连接到芯区和包层的相对面的第一和第二端盖（206,208）。芯区，包层和端盖共同形成单片熔合结构。每个端盖具有主外表面，该主外表面的面积大于芯部区域和包覆层的面的组合面积，端盖附接到该面部。
