Coherence length tunable semiconductor laser
Acta Physica Sinica, 2009 We report a technique for continuous tuning the coherence length of semiconductor laser. The coherence length of the semiconductor laser is controlled by using optical feedback scheme. The results show that the coherence length of semiconductor laser can be shortened from several meters of the original solitary laser to 100 μm by the implementation of ...

Multiobjective optimization design of an rf gun based electron diffraction beam line
Physical Review Accelerators and Beams, 2017 Multiobjective genetic algorithm optimizations of a single-shot ultrafast electron diffraction beam line comprised of a 100 MV/m 1.6-cell normal conducting rf (NCRF) gun, as well as a nine-cell 2π/3 bunching cavity placed between two solenoids, have ...

Solar flux dependence of coherence scales in scintillation patterns produced by ESF irregularities [PDF]
Annales Geophysicae, 2005 The coherence scale length, defined as the 50% decorrelation scale length along the magnetic east-west direction, in the ground scintillation pattern obtained at a dip equatorial location, due to scattering of VHF radio waves by equatorial spread F ...

Observation of long phase-coherence length in epitaxial La-doped CdO thin films
, 2017 The search for long electron phase coherence length, which is the length that an electron can keep its quantum wave-like properties, has attracted considerable interest in the last several decades. Here, we report the long phase coherence length of ~ 3.7

Observation of critical scaling in spin glasses below Tc using thermoremanent magnetization
Frontiers in PhysicsTime-dependent thermoremanent magnetization (TRM) studies have been instrumental in probing energy dynamics within the spin glass phase. In this paper, we review the evolution of the TRM experiment over the last half century and discuss some aspects ...

Absence of Long-Range Coherence in the Parametric Emission from Photonic Wires
, 2006 We analytically investigate the spatial coherence properties of the signal emission from one-dimensional optical parametric oscillators. Because of the reduced dimensionality, quantum fluctuations are able to destroy the long-range phase coherence even ...

Spectral flow of trimer states of two heavy impurities and one light condensed boson
, 2014 The spectral flow of three-body (trimer) states consisting of two heavy (impurity) particles sitting in a condensate of light bosons is considered. Assuming that the condensate is weakly interaction and that an impurity and a boson have a zero-range two ...

Ergodic vs diffusive decoherence in mesoscopic devices
, 2013 We report on the measurement of phase coherence length in a high mobility two-dimensional electron gas patterned in two different geometries, a wire and a ring.

Induced spin-orbit coupling in silicon thin films by bismuth doping
, 2018 We demonstrate an enhancement of the spin-orbit coupling in silicon (Si) thin films by doping with bismuth (Bi), a heavy metal, using ion implantation.
