We will present a study of our attempt to solve the Paraxial Wave Equation to simulate propagation of various laser beams in vacuum as well as in a turbulent medium. Our approach is to explore the suite of partial differential equation solvers in COMSOL® and cast our problem as an ... Per saperne di più
To achieve the goals of the Paris Agreement and limit global warming below 2 K compared to pre-industrial level, significant energy savings in all fields of industries will be required. One example of energy intensive processes in industrial fabrication is heat treatment. The applied ... Per saperne di più
The Service des Basses Températures of CEA-Grenoble has developed a cryostat able to produce solid hydrogen ribbons of thickness between 50 and 100 µm. These ribbons are intended to be used in high-power laser facilities to study proton-laser interactions. The current developments are ... Per saperne di più
Laser cladding is an additive manufacturing process, where a laser beam creates a melt pool, into which powder is fed from a powder nozzle. Due to the feed motion of the laser beam and the powder nozzle relative to the workpiece, coatings and 3D parts can be deposited, which consist of ... Per saperne di più
The remarkable power scaling of high power fiber lasers over the past years has become more and more challenging, because the effects of transverse mode instability (TMI) and photodarkening (PD) of the fiber are limiting the effective output power of typical industrial fiber lasers. The ... Per saperne di più
Cancer cells have an increased sensitivity to heat compared to healthy cells; at 42°C cancer cells are destroyed while normal cells can survive up to 47°C. Thus hyperthermia-based approaches that target specific spatial locations and simultaneously provide controlled thermal exposure ... Per saperne di più
The effect of plasmon-wavelength scaled gratings on the surface plasmon resonance is studied experimentally and theoretically. The model samples are multi-layers containing laser fabricated gratings at bimetal-polymer interfaces. Dual-angle dependent surface plasmon resonance ... Per saperne di più
Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... Per saperne di più
A micromirror or a torsional actuator in general has been proven to be one of the most popular actuators fabricated by Micro-Electro-Mechanical System (MEMS) technology in many industrial and biomedical applications such as RF switches, a laser scanning display, an optical switch matrix, ...

The aim of this study is to compare the diffraction efficiency of a sinusoidal diffraction grating numerically calculated using COMSOL Multiphysics® with the measured results performed with a custom-made equipment and calculations using Bessel functions. A diffraction grating with the ... Per saperne di più
