Ultrathin film lasing
Abstract
Technologies are described for methods to fabricate lasers to amplify light. The methods may comprise depositing nanoparticles on a substrate. The length, width, and height of the nanoparticles may be less than 100 nm. The methods may further comprise distributing the nanoparticles on the substrate to produce a film. The nanoparticles in the film may be coupled nanoparticles. The coupled nanoparticles may be in disordered contact with each other within the film. The distribution may be performed such that constructive interference of the light occurs by multiple scattering at the boundaries of the coupled nanoparticles within the film. The methods may comprise exposing the film to a power source.
