    Metal nanoparticles are efficient scatterers for light at around the frequency of localized surface plasmon resonance. By randomly dispersing such strong scatterers in a gain material, a laser system is achieved. Multiple scattering leads to an optical feedback that selects lasing modes. This type of laser is called random laser and has been developed using dielectric scatterers. This article highlights the application of metal nanoparticles to random laser and emphasizes the advantages of metallic scatterers compared to dielectric scatterers.
