In 2003, D. Bergman and M. I. Stockman proposed the idea of surface plasmon amplification by stimulated emission of radiation (spaser). The goal is to achieve coherent plasmon mode at the nanoscale.
In the adiabatic rapid passage (ARP), the pump radiation is tuned above the resonance frequency and swept through the resonance frequency of the gain medium.
In this article, we pump a spaser system using a Gaussian pulse. It has been shown that a chirp Gaussian pulse is more effective for population transfer in the gain medium, as demonstrated using the ARP principle. The consequence is a large number of coherent localized surface plasmons (LSPs).
