High-intensity femtosecond laser irradiation experiments have been carried out on polymer targets doped with gold nanorods in order to study the occurrence of resonant plasmon field enhancement in the course of ion acceleration. The motivation is the exploitation of the resonant plasmonic effect for increasing the nuclear fusion rate in suitable targets, pursued by the Nanoplasmonic Laser Induced Fusion Experiment project in Hungary. Various aspects of the interactions have been investigated experimentally using the laser laboratory facilities of the Wigner as well as the ELI-ALPS research centers. Different target compositions and structures have been studied and numerous diagnostic techniques have been applied to detect the interaction products. A brief summary of the experimental procedures is presented, with special attention to the laser pulse temporal contrast as an important parameter. Besides, references to some recent results are given and future plans are discussed.
