The nonlinear Talbot effect is a near-field nonlinear diffraction phenomenon in which the self-imaging of periodic objects is formed by the second harmonics of the incident laser beam.We demonstrate the first,to the best of our knowledge,exam-ple of nonli
Yolk-shell nanostructural Ni2P/C composites as the high performance electrocatalysts toward urea oxi
Highly active and low-cost catalytic electrodes for urea oxidation reaction (UOR) are always crucial for exploration of urea fuel cells. Herein, novel york-shell-structural Ni2P/C nanosphere hybrids (Ni2P/C-YS) are rationally constructed via a hydrotherma
Periodically poled lithium niobate on insulator[LNOI]ridge waveguides are desirable for high-efficiency nonlinear frequency conversions,and the fabrication process of such waveguides is crucial for device performance.In this work,we report fabrication and
We demonstrate a three-nanosecond equidistant sub-pulse multi-step Q-switched Nd∶Y3Al5O12[Nd∶YAG]laser.In the time interval of 100-1000 ns,three pulses with the same nanosecond interval and the same peak power are obtained at the pulse width of 24 ns,28 n
A millimeter-sized negatively charged polymer embedded with molybdenum disulfide nanosheets for effi
Molybdenum disulfide (MoS2) has excellent trapping ability for lead ions whereas its micro-/nanoscale size has greatly impeded its practical applications in the flow-through systems. Herein, a millimeter-sized nanocomposite MoS2-001 was synthesized for Pb
Recently,nonlinear photonics has attracted considerable interest.Among the nonlinear effects,second harmonic generation[SHG]remains a hot research topic.The recent development of thin film lithium niobate[TFLN]technology has superior performances to the c
We investigate the influences of structure parameters and interface shapes on the bandwidth of the edge state of lithium niobate valley photonic crystals.By increasing the size difference of two air holes in the same unit cell,we find that the bandwidth o
A fiber-based source that can be exploited in a stimulated emission depletion[STED]inspired nanolithography setup is presented.Such a source maintains the excitation beam pulse,generates a ring-shaped depletion beam,and automatically realizes dual-beam co
We show that inhomogeneous waveguides of slowly varied parity-time[PT]symmetry support localized optical resonances.The resonance is closely related to the formation of exceptional points separating exact and broken PT phases.Salient features of this kind
Compact long-working-distance laser-diode-based photoacoustic microscopy with a reflective objective
Photoacoustic microscopy[PAM]has quickly developed into a noninvasive biomedical imaging technique to achieve detec-tion,diagnosis,and monitoring.Compared with Q-switched neodymium-doped yttrium aluminum garnet or optical para-metric oscillator lasers,a l
