High power lasers have a wide range of applications. The goal of this work is to analyze and further optimize a beam expander made of 2 lenses used with a kW class laser. The preliminary lens design is performed using an optical design software but its performance analysis, when used ... Per saperne di più
Autoliv Livbag is a company specialized in the development and manufacturing of gas generator for airbags based on pyrotechnic and compressed gas technologies. In this context, specifications of the product are very particular. Indeed, the gas generator needs to be airtight for several ... Per saperne di più
A numerical model of laser welding process applied on highly optically reflective and thermally conductive materials such as copper has been developped. The latter considers multiphysical couplings of CFD, heat transfers and phase-field representation to account for topological ... Per saperne di più
The high heat loads intrinsically associated with high-energy, high repetition rate laser systems require sophisticated thermal management analyses to minimise the impact of thermal effects on optical performance. Non-uniform heat deposition in optical elements can lead to the onset of ... Per saperne di più
Laser-induced photovoltage in ferromagnetic thin films is often explained by magneto-thermoelectric effects such as the anomalous Nernst effect (ANE). ANE appears when thermal gradients interact with magnetization. While power loss in flat films can be estimated analytically, numerical ... Per saperne di più
As semiconductor devices continue to shrink and incorporate complex 3D architectures, conventional optical metrology faces limitations in resolving features smaller than the optical wavelength or those hidden beneath opaque layers. Ultrafast photoacoustic spectroscopy provides a ... Per saperne di più
This work presents the design and modelling of a quantum sensor based on the NV (Nitrogen-Vacancy) defect in the diamond lattice for in vitro biomedical applications. The platform employs ~150nm HPHT (High Pressure High Temperature) diamond nanoparticles (NDs) containing NV centers, ... Per saperne di più
An auto-consistent multiphysical 3D model with strong coupling between Heat Transfer, Navier Stokes and ALE problems is proposed for the description of transient development of the keyhole and the melted zone in laser welding of metallic materials. It showed a satisfactory correspondence ... Per saperne di più
Femtosecond laser are now a regular tool of the modern ophtalmic surgeon, for instance in cataract surgery by enabling precise cut of the cristalline lens tissue before removal. As femtosecond laser tissue interaction is highly dependant of the energy spatial density, a simplified model ... Per saperne di più
Wearable devices are drastically transforming the healthcare industry by enabling continuous, real-time monitoring of physiological and biochemical properties outside clinical settings. One particularly important application is the monitoring of stress; a significant factor linked to ... Per saperne di più
