Reversibly Tuning Electrochemiluminescence with Stimulated Emission Route for Single-Cell Imaging [PDF]

Research, 2023
Electrochemiluminescence (ECL) has established itself as an excellent transduction technique in biosensing and light-emitting device, while conventional ECL mechanism depending on spontaneous emission of luminophores lacks reversibility and tunable ...

Stimulated Emission up to 2.75 µm from HgCdTe/CdHgTe QW Structure at Room Temperature [PDF]

Nanomaterials, 2022
Heterostructures with thin Hg(Cd)Te/CdHgTe quantum wells (QWs) are attractive for the development of mid-infrared interband lasers. Of particular interest are room-temperature operating emitters for the short-wavelength infrared range (SWIR, typically ...

Optimal irreversible stimulated emission

New Journal of Physics, 2012
We studied the dynamics of an initially inverted atom in a semi-infinite waveguide, in the presence of a single propagating photon. We show that atomic relaxation is enhanced by a factor of 2, leading to maximal bunching in the output field. This optimal

Electrical Pumping of Perovskite Diodes: Toward Stimulated Emission [PDF]

Advanced Science, 2021
The success of metal halide perovskites in photovoltaic and light‐emitting diodes (LEDs) motivates their application as a solid‐state thin‐film laser. Various perovskites have shown optically pumped stimulated emission of lasing and amplified spontaneous

Reactivatable stimulated emission depletion microscopy using fluorescence-recoverable nanographene [PDF]

Nature Communications
Stimulated emission depletion (STED) microscopy, a key optical super-resolution imaging method, has extended our ability to view details to resolution levels of tens of nanometers.

Through-bond and through-space radiofrequency amplification by stimulated emission of radiation [PDF]

Communications Chemistry
Radio Amplification by Stimulated Emission of Radiation (RASER) is a phenomenon observed during nuclear magnetic resonance (NMR) experiments with strongly negatively polarized systems. This phenomenon may be utilized for the production of very narrow NMR

Optical Frequency Comb-Based Direct Two-Photon Cooling for Cold Atom Clock

Photonics, 2022
The performance of the cold atom clock based on coherent population trapping (CPT) improved when the temperature decreased. In order to obtain a lower temperature in the cold atom clock, we proposed a cooling scheme in this paper that employs direct two ...

Hawking radiation as stimulated emission

Physics Letters B, 2020
We regard the Parikh-Wilczek's tunnelling model of Hawking radiation as a quantum mechanical process of stimulated emission. The hypothesized microstates are found seated at the horizon with double degeneracy. A Jaynes-Cummings toy model for a black hole
