In-situ microscale diagnostic of the melting pool in laser additive manufacturing using digital holography

Pascal Picart

Le Mans Université, France

Through the last decades Laser Beam Melting (LBM) emerged as the major metal additive manufacturing process to produce small to medium size structures. In this paper, we propose two-wavelength digital holography (TWDH) for in-situ investigation of the melt pool. TWDH has the advantage of being contact-less, non-intrusive, and yields full-field surface shape data without any requirement for scanning. This paper describes the optical set-up and its installation in a LBM system. We present first experimental results for in-situ diagnostic of the melt pool with several measurements.

Hyperthermia mediated by plasmonic materials is a non-invasive technique that allows the controlled increase of temperature into biological tissues. Localized hyperthermia can be achieved using gold nanoparticles as photothermal agents. In this work we describe the photothermal effect of gold nanoprisms on the morphology and molecular modifications of the model organism Hydra vulgaris, following irradiation with a NIR laser. The results reveal the action of heat on animal physiology and open new perspectives for the development of technologies based on hyperthermia for tissue regeneration.

Compact modules for off-axis holography in microfluidics: design solutions and applications

Teresa Cacace, Paturzo Melania, Vittorio Bianco, Vito Pagliarulo, Pietro Ferraro

CNR, Italy

We present a compact and cost-effective imaging module, implementing the interferometer architecture for off-axis digital holography on a commercial microfluidic chip, using a laser diode as light source. It is demonstrated that the characteristic features of Digital Holography, i.e. label-free imaging, quantitative phase mapping and flexible refocusing, are preserved, and differences and specific fields of applicability are highlighted.

Development and simulated environment testing of β-Ga2O3-based photodetectors for space-based observation of the Herzberg continuum

Xavier Arrateig1, Luc Damé1, Mustapha Meftah1, Halima Ghorbel1, Faustine Bouyssou1, Imene Sidi-Boumeddine1, Pierre Maso2, David Rogers3, Philippe Bove3, Vinod Sandana3, Ferechteh Teherani3

This work presents the realization of β-Ga2O3-based photodetectors going from the wafer to the final packaged sensors including device architecture development, photolithography, contacting, probing, singulation, packaging, stringent robustness testing (in a simulated environment) and performance binning, so as to obtain final flight model photodetectors that will be integrated in the Inspire-Sat-7 Mission to monitor the Herzberg continuum from space
