26. Radiation Processes in Dielectric Cylindrical Waveguides

Aram Saharian

16/06/2025, 16:00

Dielectric cylindrical waveguides are widely used for confining and guiding of electromagnetic waves in relatively wide range of frequencies. They have found numerous technological and scientific applications in telecommunications, medicine, material science, photonics and quantum optics. In this presentation, we will discuss the applications of dielectric cylindrical waveguides in the...

83. Free Electron Coherent Sources and Conventional Laser devices

Giuseppe Dattoli (ENEA Frascati)

Coherent sources of radiation, from “free” electrons, are playing a prominent role in Physics and applied science.
Even though they are described as “non-conventional” lasers, they share a noticeable amount of physics with atomic or molecular lasers.
In this lecture we describe the possibility of developing a unified point of view to their treatment, by introducing an appropriate set of...

29. Interaction of Ultraintense Particle Beams with Dense Matter: Coherent Effects of Stopping and Radiation

Alessandro Curcio

16/06/2025, 17:20

The theory of Coherent Stopping Power (CSP) of ultradense charged particle beams propagating in a dense matter is presented.
CSP corresponds to a collective inelastic collision which adds to the ordinary stopping power of individual particles.
Unlike the latter, which depends only on the particles’ energy, CSP depends upon many more parameters such as the total charge of the ensemble and...
