Laser Induced Aggregation of Light Absorbing Particles by Marangoni Convection

open access: yesApplied Sciences, 2020
Laser induced Marangoni convection can be used to accumulate micro-particles. In this paper, a method is developed to control and accumulate the light absorbing particles dispersed in a thin solution layer. The particles are irradiated by a focused laser

Dependency of the stochastic heating of electrons on the pulse rise-time in intense laser-plasma interaction [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2021
In this paper, the effects of the pulse rise-time in the performance of the electron heating in the interaction of intense laser pulse with under-dense plasma have been investigated using the particle-in-cell (PIC) simulation code. In this way, two laser

Enhancement of laser heating process by laser surface modification on Titanium alloy

open access: yesJournal of Mechanical Engineering and Sciences, 2021
Titanium alloys are widely utilized in laser heating applications. However, it has poor optical properties due to low laser energy absorption. Nevertheless, a higher energy absorption can be realized by modifying the surface profile through increasing ...

Effect of auxiliary heating process on low power pulsed laser wire feeding deposition

open access: yesMaterials & Design, 2022
Low-power pulsed laser wire-feeding deposition has the advantages of low cost and less accumulation of heat. At the same time, the low laser power leads to the prominent problem of unfused defects in the deposited samples and the appearance of cold crack

Laser-Induced Heating in Optical Traps [PDF]

open access: yesBiophysical Journal, 2003
In an optical tweezers experiment intense laser light is tightly focused to intensities of MW/cm(2) in order to apply forces to submicron particles or to measure mechanical properties of macromolecules. It is important to quantify potentially harmful or misleading heating effects due to the high light intensities in biophysical experiments.
