Scientists Prevent Critical Collapse of Higher-order SolitonsSelf-trapped modes suffer critical collapse in two-dimensional cubic systems. To overcome such a collapse, linear periodic potentials or competing nonlinearities between self-focusing cubic and self-defocusing quintic nonlinear terms are often introduced. A...Mar 06, 2020 -
Scientists Solved Simultaneous Optical Trapping and Imaging In The Axial Plane For Light-matter InteractionOptical trapping has become a powerful tool in numerous fields such as biology, physics, and chemistry. But, in conventional optical trapping systems, trapping and imaging share the same objective lens, confining the region of observation to the focal plane...Mar 05, 2020 -
Scientists Predicted the Dipole Solitons Can be Stably Localized Within A Single Well of The Nonlinear LatticesNonlinear Fractional Schr？dinger Equation (NLFSE) is also adopted in soliton properties investigation recently. The formation and propagation stability of solitons in 1D saturable fractional media with nonlinear lattice schemes are unclear.To set up a phys...Mar 04, 2020 -
Scientists Experimentally Confirmed the Relationship Between Phase Noises and Harmonic Frequenciespassively mode-locked fiber lasers (MLLs) have rapidly developed and been widely used in many application fields.Over the past decades, theoretical analysis models related to noise characterization have been built. However, no detailed study on timing jitte...Mar 02, 2020 -
Scientists Reveal a Methodology for Highly Cost-Efficient Large-Scale Uniform Laminar Plasma Jet ArrayDeveloping cost-efficient large-scale uniform plasma jets represents a significant challenge for high performance in material processing and plasma medicine. Here, a V-I characteristic modulation approach is proposed by a research group of CAS to reduce the...Jan 14, 2020
