Abstract: It was recently shown (Lakhina et al (2020), Physica Scr. 95, 105601) that in a plasma of hot electrons and two counterstreaming warm proton beams, a slow ion-acoustic solitary mode occurred, where the soliton speeds… read more here.

DOI: 10.3390/ma12142254
Abstract: Many laser material processing applications require an optimized beam profile, e.g., ring shape or Top-Hat profiles with homogeneous intensity distribution. In this study, we show a beam shaping concept leading to a phase shifting element… read more here.
