Picosecond pulsed laser-assisted reshaping of metallic nanoparticles embedded in a glass matrix

摘要

Modification of silver nanoparticles embedded in a glass substrate with femtosecond pulsed laser sources has recently been of great interest. These studies were fuelled by the observation of unique optical properties in terms of femtosecond pulsed laser-induced optical dichroism in these materials, leading to modification of the surface plasmon resonance (SPR) band of the embedded nanoparticles [1, 2].
