观察到在共振吸收区短微波脉冲激发非线性大振幅离子波。当使用等于或小于离子振荡周期(τi = 2π/ωpi)的短微波脉冲时,波的最大幅度为峰峰值的δn/n ≈ 40%。激发波传播到较低密度区域,其速度是其振幅的函数,v ∝ (δn/n0)2.2–2.7。同时,入射微波脉冲截止后会激发出强电子波,并被激发的电子波尾场发射并加速高能电子。
Non-linear large amplitude ion wave excitation by short microwave pulse at the resonance absorption region has been observed. The maximum amplitude of the wave is δn/n ≈ 40% in peak-to-peak, when a short microwave pulse of the order of or less than a period of ion oscillation (τi = 2π/ωpi) is used. The excited wave propagates to lower density regions and its velocity is a function of its amplitude, v ∝ (δn/n0)2.2–2.7. At the same time, a strong electron wave is excited after shut-off of the incident microwave pulse and high energy electrons are emitted and accelerated by the excited electron wave wakefield.
