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 plasmon modes that can be strongly localized on the nanoscale, including dark modes that do not couple to far-zone electromagnetic fields. Applications and related phenomena are discussed.
对纳米系统的表面等离子体场进行了量子化，并考虑了其受激发射。我们引入了一种表面等离子体量子的量子发生器，并研究了受激辐射表面等离子体放大（spaser）现象。Spaser产生选定表面等离子体模式的时间相干高强度场，这些场可以在纳米尺度上强烈局域化，包括不与远区电磁场耦合的暗模式。文中还讨论了其应用及相关现象。
