我们证明，两个非共线重叠灯丝的干涉辅助聚结会产生波长尺度的周期性等离子体密度调制，以相当于光子晶体等离子体波导的方式引导输入脉冲。周期性自通道通过对灯丝聚结的直接观察得到证明，它揭示了取决于入射灯丝之间的交叉角和强度比的波长尺度空间宽度和周期性。
We demonstrate that interference-assisted coalescence of two noncollinearly overlapped filaments creates a wavelength-scale periodic plasma density modulation to guide the input pulses equivalently as a photonic crystal plasma waveguide. The periodic self-channeling is evidenced by the direct observation of the filament coalescence, which reveals wavelength-scale spatial widths and periodicity dependent on the crossing angles and intensity ratios between the incident filaments.
