Photoacoustic Generation with Surface Noble Metal Nanostructures

Resumo

Thin layers of noble metal (Ag, Au) nanoparticles on the surface of optical fiber edge are studied from the viewpoint of photoacoustic fiber-optic generation. In this paper we present theoretical investigation of laser radiation absorbtion by the monolayer of noble metal nanoparticles deposited on the surface of the optical fiber edge. Different nanostructures on the edge of the optical fiber are proposed for effective photoacoustic generation based on lasers with wavelength of 405, 445, 450, 510–530 nm.
