As such, any variation of the interaction conditions between the laser-accelerated proton beam and the irradiated material sample (e.g. changing the number of protons per unit of irradiated surface, varying the distance between the particle source and the sample or tuning the length of the laser...
This planar axicon outputs a Bessel-like beam with a ring-shaped intensity distribution (SI Section 6) when illuminated with a plane wave. The cross section of the device’s output agrees with the simulation in Fig.6c, verifying SCRIBE’s ability to accurately define the refractive index in t...

While the broadband nature of the electron spectrum might not be suitable for some applications, in the generation of photoneutrons, the spectral quality of the beam is of secondary importance. Figure 1. Electron density at the center of the density plateau (a), electron distribution function ...
For processing the samples with DLIP technology, a two-beam configuration was used. The used configuration utilizes an IR (1064 nm) solid-state Nd:YVO4 laser (Edgewave PX200, Würselen, Germany) with 10 ps pulses and maximum output power of 10 W. The workstation is equipped with a comme...
A laser scatterometer used, e.g., to detect defects on memory media, includes a beam block that can be finely adjusted so as to block specular light while maximizing the small angle scattered light th
We discuss the role of emittance, brightness, and other factors affecting the quality of beams in the free electron laser. Since the key parameters in the dynamics of the free electron laser interaction depend on the beam density and axial energy spread of the beam, the ratio of the current...
In recent years, laser ablation has emerged as a practical alternative solution for many types of shipyard surface preparation applications. The development of reliable, solid state lasers with closed-loop beam delivery systems enables the use of laser energy for selective and controlled removal of ...
