Effect of optical basicity and energy transfer on near
... Recently, Bismuth-doped glass has been applied as a novel promising active material for broadband near-infrared (NIR) tunable amplification and lasing[1]. The quantum yield of the NIR luminescence is very low due to the stimulated emission cross section of Bi-doped glasses and very small at 1100 - 1 ...

Beyond Optical Molasses: 3D Raman Sideband Cooling of Atomic Cesium to High Phase-Space Density.
... The large Raman coupling in our configuration is comparable to the average vibration frequency. This allows us to cool efficiently in a 3D lattice where the trapping potential is neither isotropic nor harmonic. In contrast to previous work [19,21], neither the individual vibration frequencies nor th ...

Nitrogen-vacancy center
The nitrogen-vacancy center (N-V center) is one of numerous point defects in diamond. Its most explored and useful property is photoluminescence, which can be easily detected from an individual N-V center, especially those in the negative charge state (N-V−). Electron spins at N-V centers, localized at atomic scales, can be manipulated at room temperature by applying a magnetic field, electric field, microwave radiation or light, or a combination, resulting in sharp resonances in the intensity and wavelength of the photoluminescence. These resonances can be explained in terms of electron spin related phenomena such as quantum entanglement, spin-orbit interaction and Rabi oscillations, and analysed using advanced quantum optics theory. An individual N-V center can be viewed as a basic unit of a quantum computer, and it has potential applications in novel, more efficient fields of electronics and computational science including quantum cryptography and spintronics.
