Characterization of recycled Inconel 718 metal powder for assessing its reusability in the laser powder bed fusion process

Clean Technologies and Recycling, 2022
Additive manufacturing technologies such as laser powder bed fusion (LPBF) provide unprecedented abilities to manufacture complex 3-D parts and structures; however, the process produces leftover metal powder that is often unused, resulting in significant

Quantum-inspired interferometry with chirped laser pulses

, 2008
We introduce and implement an interferometric technique based on chirped femtosecond laser pulses and nonlinear optics. The interference manifests as a high-visibility (> 85%) phase-insensitive dip in the intensity of an optical beam when the two ...
