Stimulated emission and absorption of photons in magnetic point contacts

New Journal of Physics, 2012
Point contacts between high anisotropy ferromagnetic SmCo _5 and normal metal Cu are used to achieve a strong spin-population inversion in the contact core.

Electric Field‐Stimulated Autofluorescence for In Situ 3D Characterization of Polymer Defects

Advanced Science
The absence of in situ detection approaches for internal defect structures in polymers (such as microscale fillers, voids, and electrical trees) has long impeded advanced materials characterization. Herein, it is demonstrate that moderate electric fields

Stimulated Emission or Absorption of Gravitons by Light

Physical Review Letters
We study the exchange of energy between gravitational and electromagnetic waves in an extended Mach-Zehnder or Sagnac type geometry that is analogous to an “optical Weber bar.” In the presence of a gravitational wave (such as the ones measured by the Laser Interferometer Gravitational Wave Observatory), we find that it should be possible to observe ...

Photon-assisted ultrafast electron–hole plasma expansion in direct band semiconductors

Nanophotonics
Time-resolved terahertz spectroscopy is used to investigate formation and ultrafast long-distance propagation of electron–hole plasma in strongly photoexcited GaAs and InP.

Stimulated emission tomography for efficient characterization of spatial entanglement

Physical Review Research
Stimulated-emission tomography (SET) is an excellent tool for characterizing the process of spontaneous parametric down conversion (SPDC), which is commonly used to create pairs of entangled photons for use in quantum information protocols.

Stimulated emission and coherent control of gamma photons described by quantum mechanical model

Physical Review Research
Creating a coherent source of gamma radiation remains one of the biggest motivations in gamma-ray optics. Such a source would utilize the stimulated emission of gamma photons. However, to achieve lasing in the high-energy regime other physical principles
