Stimulated coherent spontaneous emission in an FEL with 'quiet' bunches
shot noise reduction controlled microbunching instability laser heater
2012/5/31
For a planar FEL configuration we study stimulated coherent spontaneous emission driven by a gradient of the bunch current in the presence of different levels of noise in bunches. To perform a vast am...
Comment on "Particle acceleration by stimulated emission of radiation near a solid-state active medium"
Particle acceleration stimulated emission of radiation
2011/8/31
In a recent Letter,V. Berezovsky, H. Alam, and L. Sch鋍hter have reported 揳cceleration of electrons moving in free space near an active Nd:YAG slab? The reported mechanism is particle acceleration by s...
Low-Temperature Dependences of the Polarization of Terahertz Emission from $n$-Germanium in Heating Electric Fields
Low-Temperature Dependences Polarization of Terahertz Emission Heating Electric Fields
2010/11/19
As was noted in [3], in order to verify the assumption that the behavior of the polarization dependences of the terahertz emission by hot electrons from 𝑛-Ge is determined by the type of carri...
Amplified Stimulated Terahertz Emission at Room temperature from Optically Pumped Graphene
Amplified Stimulated Terahertz Emission Room temperature Optically Pumped Graphene
2010/11/22
Room temperature Terahertz stimulated emission and population inversion in optically
pumped graphene is reported. We experimentally observe fast relaxation and relatively slow recombination dynamics ...
Back reaction, emission spectrum and entropy spectroscopy
Back reaction emission spectrum entropy spectroscopy
2010/12/22
Recently, an interesting work, which reformulates the tunneling framework to directly produce the Hawking emission spectrum and entropy spectroscopy in the tunneling picture, has been received a broad...
Relativistic versus Newtonian frames: emission coordinates
null emission coordinates location systems causal class positioning system gravimetry
2010/3/17
Only a causal class among the 199 Lorentzian ones, which do not exists in the Newtonian spacetime, is privileged to construct a generic, gravity free and immediate (non retarded) relativistic position...
An advanced fully 3D OSEM reconstruction for positron emission tomography
3D OSEM PET symmetries sparse matrix
2010/5/7
A fully 3D OSEM reconstruction method for positron emission tomography (PET) based on symmetries and sparse matrix technique is described. Great savings in both storage space and computation time were...
