Generation of SPASER Pulse by Rapid Adiabatic Passage with Chirped Pump Pulse

Abstract

The concept of surface plasmon amplification by stimulated emission of radiation (spaser) was proposed by D. Bergman and M. I. Stockman in 2003 [4]. In this article, we use Gaussian pulse to pump a spaser system. We utilize the concept of ARP and show that a chirp Gaussian pulse is more efficient for population transfer in gain medium [4]. As a result, a large number of localized surface plasmons (LSPs) are obtained.
