We present the results of 3D PIC and 2D PIC simulations of the ultra short high irradiance laserpulse interaction with targets where the plasma containing multicomponent cluster targets and multi-clustercloud is embedded in an underdense plasma. In both cases the laser radiation expels the electrons from the clusters and ejects them into the wake plasma wave generated by the ultrashort laser pulse in the underdense plasma. This provides a novel mechanism for the electron injection into the wake field for acceleration.
