Our group developed an experimental millimetric capsule intended to release chemicals or drugs. The delivery mechanism of such device relies on the thermal expansion of carbon-elastomer composites which deform upon irradiation of light supplied by a Laser diode through an optical fiber. ... 詳細を見る
Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ... 詳細を見る
A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics ... 詳細を見る
Noble gasses such as argon and helium are utilized within In Gas Laser Ionization and Spectroscopy (IGLIS) [1] and Ion Guide Isotope Separation On-Line (IGISOL) [2] techniques to thermalize and transport the nuclear reactions products, which often have short lifetimes and small ... 詳細を見る
Distributed feedback lasers improve the performance of standard Fabry-Perot laser designs by including a wavelength-selective grating that provides superior output, spectral purity and temperature stability. Laterally-coupled distributed feedback (LC-DFB) lasers with the use of higher ... 詳細を見る
COMSOL Multiphysics® is being utilised to develop Thermal Model for Directed Energy Deposition (DED) process with an objective to analyse the heat transfer phenomenon during and after the process. With the rapid growth of industrial acceptance of DED process, different research ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
TC4钛合金有重量轻、塑性好、比强度高、耐腐蚀性好等诸多优良特性，因此被广泛用于航空航天、生物学、医学等领域。飞秒激光的脉宽为飞秒量级，远小于电子-声子耦合时间（皮秒量级），即在飞秒激光脉冲作用时间内晶格来不及升温，可实现真正意义上的“冷”加工。由于飞秒激光常用于微小区域的精密加工，在很短的时间内难以利用仪器直接检测材料温度，因此需要开发能够精确模拟材料温度的数值模型。利用COMSOL Multiphysic飞秒激光烧蚀钛合金的双温模型，建立一个二维轴对称数值计算模型，研究不同激光能量密度单脉冲飞秒激光的对Ti6Al4V基体的烧蚀情况。从烧蚀形貌 ... 詳細を見る
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 ... 詳細を見る
