Integrated on-chip femtosecond (fs) laser optoelectronic system, with photodetector as a critical component for light-electrical signal conversion, is long-sought-after goal wide range of frontier applications. However, the high peak intensity and complicated nanophotonic waveguide structure fs are beyond detectability integrability conventional photodetectors. Therefore, flexible response on intense in urgent needs. Herein, we demonstrate first (to our knowledge) two-photon absorption (TPA)...
A novel approach using REE data of uranium ores instead UOC samples to trace the origins unknown UOCs was developed.
Two-photon polymerization (TPP) based on laser direct writing is currently one of the most prevailing 3D micro/nano fabrication techniques. Nanomaterials can be doped in resins and assembled by TPP for developing advanced functional devices. However, there lacks an effective visualization tool to determine distribution orientation nanomaterials as-doped composite resins. Herein, we present a nondestructive, situ, rapid characterization method within cured using polarized second-harmonic...
The uranium isotope ratio of both bulk material and individual particles provides important information for nuclear safeguards forensics. As a rapid in situ analytical technique, laser ionization mass spectrometry (LIMS) was used to determine the solid samples single U3O8. results measuring showed excellent agreement with certified values. deviation less than 1% uncertainty measurement 5%. diameters about 50 μm measured by scanning electron microscopy (SEM) combined LIMS. According our...
Multi-gigahertz ultrafast fiber lasers are critical for many significant applications, including bioimaging, optical communications, and laser frequency combs. The gain which is expected to simultaneously satisfy large mode-field area, highly coefficient resistance photodarkening, will effectively protect mode-locked materials/devices that generally possesses low damage threshold (<10 mJ/cm 2 ) enhance stability in the centimeter-scale lasers. However, still remains a challenge. In this...
As a compression method that can significantly reduce the cost of calculations and memories, model binarization has been extensively studied in convolutional neural networks. However, recently popular vision transformer models pose new challenges to such technique, which binarized suffer from serious performance drops. In this paper, an attention shifting is observed binary multi-head self-attention module, influence information fusion between tokens thus hurts performance. From perspective...
Capillary water absorption plays a critical role in the ingress of corrosive elements during construction concrete structures environments. This study presented novel approach for analyzing capillary flow within unsaturated based on principle stationary action. The pores can be regarded as variational problem, while action provides method determining path solution. evolution and distribution characteristics content wetting front were explicitly determined using exponential power hydraulic...
Research in the field of laser atmospheric propagation has been continued for many years. Due to turbulence, actual systems are facing a lot technical problems. It leads difficulty large-scale civilian use communication. In this paper, parameters transmission experiment analyzed. The study is usually based on first-order Rytov approximation. we analyze optical both and second-order
Precisely-microstructured hydrogels via ultrafast laser processing have triggered a wide range of multi-functional applications such as artificial muscle, self-folding or biological robotics. Herein, we modify polarization pulsed and wavelength to optimize the structural fixity feature improvement nanowires/microarchitectures in processing. Paralleling linear with scanning direction suitable is demonstrated key factor improving size during 3D formation two-photon hydrogelation.
