Quantum-coherence-enhanced surface plasmon amplification by stimulated emission of radiation.
We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium and show that quantum coherence significantly enhances the generation of surface plasmons. Surface plasmon amplification by stimulated emission of radiation is achieved in the absence of population inversion on the spasing transition, which reduces the pump requirements....
متن کاملSurface plasmon amplification by stimulated emission of radiation: quantum generation of coherent surface plasmons in nanosystems.
We make a step towards quantum nanoplasmonics: surface plasmon fields of a nanosystem are quantized and their stimulated emission is considered. We introduce a quantum generator for surface plasmon quanta and consider the phenomenon of surface plasmon amplification by stimulated emission of radiation (spaser). Spaser generates temporally coherent high-intensity fields of selected surface plasmo...
متن کاملExactly solvable toy model for surface plasmon amplification by stimulated emission of radiation.
We propose an exactly solvable electrodynamical model for surface plasmon amplification by stimulated emission of radiation (spaser). The gain medium is described in terms of the nonlinear permittivity with negative losses. The model demonstrates the main feature of a spaser: a self-oscillating state (spasing) arising without an external driving field if the pumping exceeds some threshold value...
متن کامل[laser-light Amplification by Stimulated Emission of Radiation].
The laser is a new tool which can be a precise and accurate instrument for tissue removal under colposcopic direction in the areas of the cervix, vagina and vulva. Healing is rapid since the laser inflicts minimal tissue destruction. Postoperative pain is minimal and healing is without scar formation. The expense of the equipment and training of the operating surgeon are its only drawbacks.
متن کاملPlasmon Amplification through Stimulated Emission at Terahertz Frequencies in Graphene
We show that plasmons in two-dimensional graphene can have net gain at terahertz frequencies. The coupling of the plasmons to interband electron-hole transitions in population inverted graphene layers can lead to plasmon amplification through the process of stimulated emission. We show that the net gain values can exceed 10 cm−1 in the 1-10 terahertz frequency range, for electron-hole densities...
