Abstract

We analyze lasing of chains of gold nanoparticles and active quantum dots (QDs) regularly situated and resonantly interacting. It is shown that the minimal threshold of lasing can be close to zero, and the width of lasing line in the dependence of lasing spectral position on the resonance frequency of QDs can be essentially narrower than the plasmon resonance line.
