One of the key processes leading to the electron acceleration is the Raman scattering in its non-linear phase. The development of the Raman instability requires an unimpeded kinetic evolution in the electron phase space, which is a condition well fulfilled in the outer corona of the plasma generated by the 1st harmonics of a near-infrared laser. In this case, the generated plasma is only weakly collisional and the Raman scattering is accompanied by a complex kinetic evolution in the phase-space, such as a saturation of Landau damping, which is then translated in an unfavourable time dependence of the reflected light intensity and several fast ion groups. However, even when working with the 3rd harmonics illumination in the visible or near-UV range, by which the plasma is rendered more collisional and a part of the mentioned kinetic behaviour is suppressed, some residual fast groups may still be observed.
