Ultrafast laser processing of ceramics: Comprehensive survey of laser parameters

Journal of Laser Applications, 2020
The productivity and quality of laser micromachining depend on multiple laser parameters that are intricately correlated. For these optimizations, a quick survey of laser parameters is vital. Recently, the authors developed a Yb-doped fiber chirped-pulse amplification system that can control various laser parameters in a wide range (pulse duration: 0.4–

Parallel processing of embossing dies with ultrafast lasers

Laser-based Micro- and Nanoprocessing XII, 2018
Functionalization of surfaces equips products and components with new features like hydrophilic behavior, adjustable gloss level, light management properties, etc. Small feature sizes demand diffraction-limited spots and adapted fluence for different materials. Through the availability of high power fast repeating ultrashort pulsed lasers and efficient

Filamentation in Ultrafast Laser Material Processing

2010
When an ultrashort laser pulse is focused inside the bulk of a transparent material, filamentation occurs as a result of the dynamic balance between the Kerr self-focusing and defocusing effects in the electron plasma, which is generated through the ionization process.

Ultrafast lasers as a versatile processing tool

SPIE Proceedings, 2000
Ultrafast lasers are a class of laser that produce pulse widths of picoseconds (10 -12 sec) and femtoseconds (10 -15 sec). They can achieve extremely high peak power with low pulse energies. The most important characteristics of ultrafast laser-matter interaction are precise ablation threshold and absence of heat diffusion into the material during ...
