  • Non-probe compensation of optical vortices carrying orbital angu... In this paper, we demonstrate a scheme for compensating distorted optical vortex beams carrying orbital angular momentum. By inputting the intensity profile into the Gerchberg–Saxton algorithm [Optik 35, 237 (1972)
  • Intense keV IAP generation by orthogonally polarized multicycle ... ... field. It is demonstrated that multiple continuum-like humps, which consist of about twenty orders of harmonics and an intensity of about one order higher than the adjacent normal harmonics, are generated when longer wavelength driving fields are used. ...
  • Thermal light subwavelength diffraction using positive and negat... ... therefore have aroused particular interest. By extending the correspondence imaging scheme, we utilize the positive and negative intensity correlations in diffraction and perform subwavelength diffraction with pseudo-thermal light. In the experiment, a ...
  • Scintillations of optical vortex in randomly inhomogeneous mediu... ... has been performed. It has been found that the dependence of the scintillation index at the axis of the optical vortex on the turbulence intensity at the path has the form of a unit step. It has been shown that the behavior of scintillations in the cross ...
  • Average bit error rate of multi-hop parallel decode-and-forward-... ... on the multi-hop parallel decode-and-forward cooperative communication method with an M-ary phase shift keying subcarrier intensity modulation is studied systematically. With the max–min criterion as the best path selection scheme, the probability density ...
  • Enhancement on the generation of sampled phase-only holograms Past research has demonstrated that if the intensity image of an object is uniformly down-sampled and converted into a Fresnel hologram, the phase component alone will be sufficient to reconstruct the source image. However, due to down-sampling, the edge ...
  • New proposal of modulation of amplitude-squeezed state of light ... ... the quantum limit of noise. We propose a new mechanism of modulating an amplitude-squeezed signal with the instantaneous intensity variation of a coherent signal. The modulating signal is a coherent light where the amplitude-squeezed light takes the role ...
  • Output temporal contrast simulation of a large aperture high pow... ... contrast degradation by near-field quality deterioration, such as intensity modulation and wavefront deviation, in a large aperture ... focused by an off-axis parabolic mirror. The temporal contrast degradation by intensity modulation and wavefront deviation ...
  • High harmonic generation and ionization effects in cluster targe... ... up to more than 14 bar backing pressure. The observation of increase of harmonic intensity with increasing pressure and laser intensity shows evidence of the presence of clusters in Xe with an increased efficiency compared with He, whereas Ar ...
  • High energy density physics research at IMP, Lanzhou, China ... carbon ion beam from the Cooling Storage Ring is discussed. Investigation of the low energy heavy ion beam and plasma interaction is reported. With HEDP research as one of the main goals, the project HIAF (High Intensity heavy-ion Accelerator Facility)
