Abstract The cross-spectral density (CSD) matrix of radially polarized Lorentz correlated beam (RPLCB) is proposed, and the degree coherence RPLCB described by function. elements in anisotropic turbulent ocean are obtained. intensity polarization studied via numerical simulations. evolution free space will evolve from ring shape into caused function, be destroyed turbulence become a Gaussian profile at longer distance. with smaller length turn faster on propagation. decrease as distance...
The partially coherent Lorentz-Gauss vortex beam generated by a Schell-model source has been introduced. Based on the extended Huygens-Fresnel principle, cross-spectral density function of propagating in oceanic turbulence is derived. influences coherence length, topological charge M, and spreading properties position for are analyzed detail. results show that stronger will evolve into Gaussian-like more rapidly as propagation distance increases, number vortices change.
Based on the extended Huygens–Fresnel principle, analytical expressions for partially coherent four-petal Gaussian vortex beams propagating in oceanic turbulence are obtained, and influence of coherence length, beam order N, topological charge M parameters evolution properties discussed detail using numerical examples. The results show that will evolve into a Gauss-like rapidly with decreasing length , or increasing parameter far field due to turbulence.
The effects of different bridging fluorene units on the two-photon absorption (TPA) properties and ultrafast response organic conjugated oligomers were investigated for three star-shaped named TFT-1, TFT-2 TFT-3. These are composed same central core 1,3,5-triazine, with arms that consist specific numbers groups triphenylamine as electron-donating group at terminal end each arm. studies these carried out by using excited fluorescence (TPF), degenerate pump–probe techniques, transient...

As two-photon absorption (TPA) materials, phthalocyanine molecules have promising application prospects due to their large TPA cross-section, high third-order nonlinear optical susceptibility, and ultrafast response characteristics. In this work, properties the of three modified zinc (P-HPcZn, Pc-P-Pc, (DR1)4PcZn) were analyzed. No obvious side-shoulder peaks in Q-band can be observed from steady-state spectra molecules, confirming lack aggregation products solutions our measurement....
Multi-branched oligomers F1, F2 and F3 were investigated by spectroscopic experiments as well quantum chemical calculations to elucidate the structure–property relationships intramolecular charge transfer (ICT) characteristics of typical nonlinear optical materials. A better ICT property is obtained replacing terminal electron donors with stronger electron-donating ability. The degree effectively increased, which can be clearly seen from frontier molecular orbitals contribution central...
