    High efficiency, high repetition rate, all-fiber picoseconds pulse MOPA source with 125 W output in 15 μm fiber core

    A passive mode-locked fiber laser-delivered 13 ps pulse is saturatedly amplified with a four-stage amplifier chain. 125 W high power all-fiber picoseconds pulse laser is demonstrated in a 15-μm fiber core, and...

    Visible supercontinuum generation in tapered photonic crystal fiber pumped by picosecond pulse at 1064 nm

    Short photonic crystal fibers (PCFs) with different tapered waist diameter are made to extend the continuum spectrum in the visible range. The diversification of output continuum spectrum with the diameter of ...

    Synchronization Behavior of a Clustered Neuronal Network in a Noisy Environment

    Synchronization behavior is discussed in a clustered neuronal network, in which Rulkov maps with additive noise are applied as building blocks. Additive noise applied here is used to make the Rulkov map genera...

    Effects of channel noise on firing coherence of small-world Hodgkin-Huxley neuronal networks

    We investigate the effects of channel noise on firing coherence of Watts-Strogatz small-world networks consisting of biophysically realistic HH neurons having a fraction of blocked voltage-gated sodium and po...

    Effects of Noise on Synchronization and Spatial Patterns in Coupled Neuronal Systems

    The effects on synchronization and spatiotemporal patterns in coupled neurons are investigated. Firstly, noise-induced and noise-enhanced synchronization can be observed in coupled neuronal systems as the nois...

    Spatio-temporal patterns in a square-lattice Hodgkin-Huxley neural network

    The collective behaviour of a square-lattice Hodgkin-Huxley neural network model with white noise is investigated by numerical methods. It is found that for an intermediate value of noise the Hodgkin-Huxley ne...

    Plasma model of carrier transportation in photoelectric semiconductor detectors

    A new model, called the plasma model, describing carrier transportation in photoelectric semiconductor detectors is proposed. Semiconductor material under laser irradiation is regarded as a plasma of low tempe...
