根据Semenova-Lampe理论，由两个飞秒（约10/30 fs）激光脉冲圆柱形聚焦并相互交叉产生的光学致密电离波（IW）可能成为有效的相干X射线转换器。在脉冲交叉点附近的准平面IW的所得速度随着脉冲之间的角度从电离脉冲的群速度变化到无穷大，从而允许调谐X射线的波长及其聚束。低频长相干光脉冲散射后的X射线谱随电离脉冲的持续时间从单色向类高次谐波变化。
An optically dense ionization wave (IW) produced by two femtosecond (approximately 10/30 fs) laser pulses focused cylindrically and crossing each other may become an efficient coherent x-ray converter in accordance with the Semenova-Lampe theory. The resulting velocity of a quasiplane IW in the vicinity of pulse intersection changes with the angle between the pulses from the group velocity of ionizing pulses to infinity allowing a tuning of the wavelength of x rays and their bunching. The x-ray spectra after scattering of a lower frequency and long coherent light pulse change from the monochromatic to high order harmoniclike with the duration of the ionizing pulses.
