In laser acceleration of ions by the radiation pressure acceleration (RPA) mechanism, the efficiency of energy and momentum transfer to ions increases if the shape of the laser pulse is suitably tailored. Numerical results are presented for the Gauss

The effect of group velocity of the incident laser pulse, which being smaller than the vacuum speed of light, plays an important role in laser-driven ion acceleration as it limits the value of the maximum attainable velocity of the ultrathin solid de

Analytical and numerical investigation of the reflection and transmission of a counter-propagating relativistically strong laser pulse from a relativistically flying dense plasma double-sided mirror is studied. We assume that the incident laser pulse

A non-local theory is used to study the effects of the corrugation parameter ε of a plasma-filled slow wave structure, the cyclotron frequency of a pumped magnetic field Ω and the relativistic gamma factor γ0 on the instability growth Γ of a free

A nonlocal theory of stimulated Raman backscattering (BSRS) parametric instability of a large amplitude electromagnetic (EM) mode in a strongly magnetized plasma e.g., one encountered in a plasma filled backward wave oscillator, is reported. The EM m

Two copropagating lasers, having frequency difference Δω≈ωp, drive a plasma wave. The plasma beat wave amplitude increases with time initially due to the laser beams. As time grows, the plasma beat wave acquires large amplitude and it becomes su
