Nonlinear optics (NLO) is a well-established research field, which has benefited from plasmonics and nanoplasmonics to enhance nonlinear optical processes in bulk and nanomaterials. Another subject which has grown in the last few years and employs plasmonic enhancement are the field of nanolasers and random lasers.
In this talk, I shall briefly review the basics concepts of plasmonics and nanoplasmonics, and spend most of the time giving recent examples of nanoplasmonics in NLO using gold nanorods and gold metasurfaces, as well as plasmonically enhanced nano and random lasers, with the last one exploiting rigid and flexible random lasers geometries.
