Ion-motion-driven enhancement of energy coupling and stability in relativistic laser-microchannel interaction
K. Weichman, M. VanDusen-Gross, G. Bruhaug +5
For sufficiently short relativistic-intensity laser pulses, the disparity in time scales for electron and ion motion causes ions to behave as a fixed, neutralizing background. As t…
Collimated -ray emission enabled by efficient direct laser acceleration
Kavin Tangtartharakul, Gaetan Fauvel, Talia Meir +5
We investigate the mechanisms responsible for single-lobed versus double-lobed angular distributions of emitted -rays in laser-irradiated plasmas, focusing on how direct laser…
Generation of 10 kT Axial Magnetic Fields Using Multiple Conventional Laser Beams: A Sensitivity Study for kJ PW-Class Laser Facilities
Jue Xuan Hao, Xiang Tang, Alexey Arefiev +4
Strong multi-kilotesla magnetic fields have various applications in high-energy density science and laboratory astrophysics, but they are not readily available. In our previous wor…
Advances in laser-plasma interactions using intense vortex laser beams
Yin Shi, Xiaomei Zhang, Alexey Arefiev +1
Low-intensity light beams carrying Orbital Angular Momentum (OAM), commonly known as vortex beams, have garnered significant attention due to promising applications in areas rangin…
Compact in-vacuum gamma-ray spectrometer for high-repetition rate PW-class laser-matter interaction
G. Fauvel, K. Tangtartharakul, A. Arefiev +10
With the advent of high repetition rate laser facilities, novel diagnostic tools compatible with these advanced specifications are required. This paper presents the design of an ac…
