Laser Absorptivity Measuring Device
Characterizing the laser absorptivity and efficiency compensation of laser-based processes can provide useful avenues for defect characterization and mitigation; however, laser-metal interactions during welding and metal additive manufacturing are notoriously complex. Existing techniques for measuring laser absorption efficiency rely on reflective rather than direct measurements, require the use of simulative samples that add assumptions, and/or involve large processing setups that behave differently than the genuine process.
