Super-Heavy Ions Acceleration Driven by Ultrashort Laser Pulses at Ultrahigh Intensity
Pengjie Wang, Zheng Gong, Seong Geun Lee +17
The acceleration of super-heavy ions (SHIs) from plasmas driven by ultrashort (tens of femtoseconds) laser pulses is a challenging topic waiting for breakthrough. The detecting and…
Optical Shaping of Plasma Cavity for Controlled Laser Wakefield Acceleration
Bobbili Sanyasi Rao, Myung Hoon Cho, Hyung Taek Kim +7
Laser wakefield accelerators rely on relativistically moving micron-sized plasma cavities that provide extremely high electric field >100GV/m. Here, we demonstrate transverse shapi…
Generation of 0.7 mJ multicycle 15 THz radiation by phase-matched optical rectification in lithium niobate
