The Influence of the Processing Parameters on the Laser-Ablation of Stainless Steel and Brass during the Engraving by Nanosecond Fiber Laser

Luka Hribar et al.

Summary: This paper investigates the influence of various parameters on the ablation of steel and brass with a nanosecond fiber laser. The results show that pulse duration and repetition rate have an effect on the material removal rate (MRR), and shielding by plasma and ejected material plays a role in reducing MRR. The surface roughness is mainly influenced by line-to-line and pulse-to-pulse overlaps.

Review of Quality Optimization of Electron Beam Based on Laser Wakefield Acceleration

Kangnan Jiang et al.

Summary: Compared with state-of-the-art radio frequency accelerators, the gradient of laser wakefield accelerators is significantly higher, making them crucial for the development of miniaturized particle accelerators and radiation sources. With the rapid advancement of free-electron laser devices, there is an increasing demand for higher quality electron beams. This review examines the optimization of electron beam quality through laser wakefield acceleration and presents representative studies, including manipulation of the electron beam phase space using injection, plasma profile distribution, and laser evolution. These studies are beneficial for further advancing the application of laser wakefield accelerators.

Free-electron lasing at 27 nanometres based on a laser wakefield accelerator

Wentao Wang et al.

Summary: X-ray free-electron lasers are essential tools in structural biology and chemistry, generating intense radiation at sub-angstrom wavelengths. While laser wakefield accelerators are seen as a promising option for driving compact X-ray free-electron lasers, challenges remain due to the relatively poor quality of electron beams. The experimental demonstration of undulator radiation amplification using electron beams from a laser wakefield accelerator shows potential for developing compact X-ray free-electron lasers with a wide range of applications.
