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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
