The development of ultra-intense laser-based sources of high energy ions is an important goal, with a variety of potential applications. One of the barriers to achieving this goal is the need to maximize the conversion efficiency from laser energy to

Laser acceleration of ions to ≳MeV energies has been achieved on a variety of Petawatt laser systems, raising the prospect of ion beam applications using compact ultra-intense laser technology. However, translation from proof-of-concept laser exper

The influence of various defects on the femtosecond laser damage resistance of a HfO2/SiO2/Ta2O5-based 48-layer grating designed for 800 nm is studied using the finite-difference time-domain method incorporated with the Keldysh photoionization theory

Multilayer dielectric (MLD) gratings with high diffraction efficiency and a high laser-induced damage (LID) threshold for pulse compressors are key to scaling the peak and average power of chirped pulse amplification lasers. However, surface defects

We investigate direct acceleration of electrons produced during ionization of Neon gas using tightly focused and radially polarized Petawatt-class short pulse lasers. Backwards propagation is demonstrated at specific initial conditions of Neon ions.

Laser-accelerated electron beams have been created at a kHz repetition rate from the {\it reflection} of intense ($\sim10^{18}$ W/cm$^2$), $\sim$40 fs laser pulses focused on a continuous water-jet in an experiment at the Air Force Research Laborator
