Enhanced Second Harmonic Generation from Au Nanoparticle Arrays by Femtosecond Laser Irradiation

Nanoscale , 2013, Accepted Manuscript

DOI: 10.1039/C3NR02145A, Communication

Gary Walsh, Luca Dal Negro

Ultrafast laser irradiation of planar Au nanoparticle arrays is shown to double the particle plasmon quality factor and to enhance second harmonic generation 40-fold. It is found that the irradiation...
