Technology assessment of laser-assisted materials processing in space

摘要: Lasers are useful for performing operations such as joining, machining, built-up freeform fabrication, shock processing, and surface treatments. These attributes attractive the supportability of longer-term missions in space due to multi-functionality a single tool variety materials that can be processed. However, current laser technology also has drawbacks space-based applications, specifically size, power efficiency, lack robustness, problems processing highly reflective materials. A review recent developments will used show how these issues may reduced indicate where further improvement is necessary realize laser-based capability space. The broad utility beams synthesizing various classes engineering illustrated using state-of-the art maps select lightweight alloys typically found on spacecraft. With advent breakthroughs diode-pumped solid-state lasers fiber optic technologies, potential perform multiple techniques increasing significantly. with suitable wavelengths beam properties have tremendous supporting future moon, Mars beyond.
