We prove that stimulated emission is by far the dominant quenching mechanism for providing super-resolution in fluorescence microscopy with a red-shifted depletion beam. Our evidences are based on simultaneously measuring fluorescence quenching and photon gain in the quenching beam. Measurements were performed for several fluorescent dyes including fluorescent proteins over a wide spectral rang...

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...

We experimentally demonstrate suppressed absorption and stimulated emission of surface plasmon polaritons (SPP) leading to all-plasmonic modulation of an SPP signal propagating at the interface between a metal and a gain medium; these observations are supported by the developed theory. The use of copropagating signal and control waves can provide more than 10 times more efficient SPP stimulated...

This note analyzes the angular distributions of the probabilities of twophoton states come out of the single-photon’s stimulated emission amplification by means of a single-atom amplifier, to see that whether the quantum theory can forbid us exploiting EPR photon pairs combined with stimulated emission to realize superluminal signaling. Besides, we stressed that superluminal signaling will lead...

Precipitates are closely related to ductile damage and dynamic recrystallization (DRX) in magnesium alloys. Using molecular dynamics simulation the embedded atomic method, competition between DRX stimulated by precipitate of alloys is investigated. The effects distribution dimensions on void nucleation, dislocation emission, growth, quantitatively discussed. It found that compared system with a...
