Beam profile analyzer for CO2 lasers
Journal of Applied Research and Technology, 2015 AbstractThe development of an optoelectronic system to analyze the beam intensity profile of CO2 lasers is presented herein. The device collects the beam profile with a LiTaO3 pyroelectric detector and uses a sampling technique based on the acquisition of horizontal sections at different levels.

Influence of the beam profile formulation when modeling fiber-guided laser welding
, 2011 During deep penetration laser welding, the focused laser beam determines the vapor capillary, called keyhole, and in turn the whole process physics. Beside spot diameter and Rayleigh length, the beam profile is another important but hardly explored part ...

All-optical structuring of laser-driven proton beam profiles
Nature Communications, 2018 Shaping particle beams generated from laser-plasma accelerators is challenging. Here the authors demonstrate an all-optical method to structure the accelerated proton beam by modulating and imprinting the spatial laser profile onto the proton beam.

Laser Beam Profiling in the Production Process [PDF]
Laser Technik Journal, 2010 AbstractLaser material processing is increasingly becoming more accepted in modern production lines. A growing number of production steps previously carried out by mechanical methods are being replaced by laser beam processing. The use of such high power laser beams requires adequate beam measurement technology to ensure product quality and to minimize

Laguerre-Gaussian and beamlet array as second generation laser heater profiles
Physical Review Accelerators and Beams, 2018 The microbunching instability is known to be detrimental to x-ray free electron laser performance. At the Linear Coherent Light Source, the microbunching instability is suppressed with a laser heater, which increases the uncorrelated energy spread of e ...

Effects of Top-hat Laser Beam Processing and Scanning Strategies in Laser Micro-Structuring
Micromachines, 2020 The uniform energy distribution of top-hat laser beams is a very attractive property that can offer some advantages compared to Gaussian beams. Especially, the desired intensity distribution can be achieved at the laser spot through energy redistribution
