Nanomaterials with outstanding optical properties are widely used in ultrafast photonics.
Especially, metal nanomaterials have attracted increasing attention in recent years owing to
the surface plasmon resonance that further enhances their nonlinear optical response,
making them suitable for generating ultrafast pulses in a wide range of wavebands. Herein,
the fabrication and integration processes of typical metal nanomaterials such as gold, silver,
and copper, as well as their applications in ultrafast lasers are reviewed. The synthesis …

Metal nanomaterials exhibit excellent surface plasmon resonance-enhanced nonlinear
optical properties, which play a key role in the modulation of incident light and realization of
ultrafast lasers. In article number 2200443, Bo Fu, Han Zhang, and co-workers review the
state of the art of ultrafast photonics enabled by metal nanomaterials, where synthesis,
integration, applications, as well as challenges and perspectives are discussed.
