Intense laser interactions at grazing incidence for attosecond photon and electron pulse generation

High harmonic generation (HHG) from laser plasma interactions can result from high intensity laser light driving nonlinear relativistic oscillations at the surface of a solid density plasma. When sufficiently intense this interaction can simultaneously produce light pulses of very short (attosecond) duration and attosecond bunches of electrons. Applications of such efficient ultra-short duration radiation sources include pump-probe measurements and extremely high resolution spectroscopy. In this work we present results of Particle in Cell simulations of the production of these sources from laser interactions at grazing incidence with solid density targets.
