    • A containment plenum is adapted to deliver laser light to an interaction region of an inhabitable structure to remove material from the structure. The containment plenum includes a plenum housing adapted to be coupled to a source of laser light. The containment plenum further includes a window substantially transparent to the laser light. The window is mounted within the plenum housing to transmit the laser light in a downstream direction and to provide a barrier to upstream transport of particulate matter generated by interaction of the laser light and the structure. The containment plenum further includes a nozzle fluidly coupled to a source of compressed gas. The nozzle is mounted downstream of the window whereby the laser light and the compressed gas are transmitted through the nozzle in the downstream direction to the interaction region of the structure. The containment plenum further includes a resilient interface coupled to the plenum housing and adapted to resiliently contact the structure and to substantially surround the interaction region, thereby confining the material and removing the material from the interaction region.
    • 容纳气室适于将激光传送到可居住结构的相互作用区域以从结构中去除材料。 容纳气室包括适于联接到激光源的增压室。 容纳气室还包括对激光大致透明的窗口。 窗口安装在增压室壳体内以沿下游方向透射激光,并且通过激光和结构的相互作用产生的颗粒物质的上游输送提供屏障。 容纳气室还包括流体耦合到压缩气体源的喷嘴。 喷嘴安装在窗口的下游,由此激光和压缩气体沿着下游方向通过喷嘴传递到结构的相互作用区域。 容纳气室还包括弹性界面,该弹性界面连接到增压室壳体并且适于弹性地接触结构并且基本上围绕相互作用区域,从而限制材料并从相互作用区域移除材料。
