A Reinterpretation of Stimulated Emission as Spontaneous Emission Under Non Thermodynamic Equilibrium Conditions
In 1916, Einstein postulated the existence of induced emission (einstrahlung), where a quantum of radiation from a light beam induced a molecule in an excited state to emit a quantum of radiation of the same frequency. The stimulating photon was unchanged by the ghostly interaction and the net effect of induced emission, which is now commonly known as stimulated emission, was indistinguishable ...
متن کاملSpontaneous and stimulated emission spectroscopy of a Nd(3+)-doped phosphate glass under wavelength selective pumping.
The influence of the host matrix on the spectroscopic and laser properties of Nd(3+) in a K-Ba-Al phosphate glass has been investigated as a function of rare-earth concentration. Site-selective time resolved laser spectroscopy and stimulated emission experiments under selective wavelength laser pumping show the existence of a very complex crystal field site distribution of Nd(3+) ions in this g...
متن کاملEnhancement of spontaneous and stimulated emission of a rhodamine 6G dye by an Ag aggregate
We have demonstrated that by adding the solution of aggregated silver nanoparticles to the solution of rhodamine 6G dye, one can enhance the efficiency of spontaneous and stimulated emission. We attribute an increase of the spontaneous emission intensity of dye to the increase of the absorption efficiency caused by the field enhancements in metallic nanostructures associated with surface plasmo...
متن کاملOptical gain, spontaneous and stimulated emission of surface plasmon polaritons in confined plasmonic waveguide.
We develop a theoretical model to compute the local density of states in a confined plasmonic waveguide. Based on this model, we derive a simple formula with a clear physical interpretation for the lifetime modification of emitters embedded in the waveguide. The gain distribution within the active medium is then computed following the formalism developed in a recent work [Phys. Rev. B 78, 16140...
متن کاملCharacteristics of Dual Amplified Spontaneous Emission from MEH-PPV Solutions
We report the observations of dual wavelength amplified spontaneous emission from the solutions of a conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in Tetrahydrofuran and 1, 2 Dichlorobenzene. We have prepared MEH-PPV using a modified procedure and purified several times in each step, the material offers low molecular weight, low polydispersity index an...
