High-order harmonic generation in Ag nanoparticle-containing plasma

Abstract

High-order harmonic generation up to the 55th order was achieved using 15 nm and 110 nm silver nanoparticle-containing plumes, when femtosecond radiation propagated through the preformed plasma. These results are compared with the high-order harmonics generated from the plasma produced on the surface of bulk silver at different delays between the subnanosecond prepulse and the femtosecond pulse.
