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 ... Mehr lesen
A critical constraint in handling high power laser beams approaching 100kW of peak average power is thermal management due to laser absorption. Seurat Technologies uses a unique, optically addressed spatial light modulator (OASLM) with liquid crystals to dynamically shape laser beams for ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
Laser-Induced Forward Transfer (LIFT) is a direct-write technique for transferring small volumes (even picolitres) of material through laser irradiation. The characteristics of this material can be in a wide range of viscosities and can respond to different rheological behaviors, from ... Mehr lesen
A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... Mehr lesen
In this poster we present the results of the strategy for calibrating the COMSOL Multiphysics® model to simulate the laser bonding process (LADB) of Mems chips. A specific aspect of this work is to calibrate the COMSOL Multiphysics® heat model loss by measuring with a miniature ... Mehr lesen
Laser Powered Homogenous Pyrolysis (LPHP), a non-isothermal wall-less plug flow reactor using cw-IR CO2 laser heating by fast vibrational–translational (V–T) energy transfer, is a common technique for high temperature pyrolysis in the gas phase with minimal catalytic effect of hot ... Mehr lesen
The laser powder bed fusion (LPBF) process involves a highly localized laser heating, resulting in a large thermal gradient that induces residual thermal stress and deformation in the finished build. The excessive residual deformation in the direction normal to in the process plane could ... Mehr lesen
Abstract. A Laser Focusing system (LFS) focuses a single laser beam (single Channel) or multiple laser beams (multi - channel) onto a surface (Specimen). The general motive of a LFS is to focus a train of brief pulses or a continuous beam of light onto a Specimen which heats up its ... Mehr lesen
