Abstract
We have studied the influence of detuning of quasimonochromatic seeding vacuum ultraviolet (VUV)/X-ray radiation from the frequency of the inverted transition of the hydrogen-like active medium of the plasma-based X-ray laser dressed by an intense infrared (IR) laser field on the formation of a subfemtosecond pulse train. For the active medium (plasma) of Li2+ ions with the inverted transition wavelength of 13.5 nm, it is demonstrated that the use of the seeding radiation detuned from the resonance by double the frequency of the modulating field allows a fourfold increase in the peak intensity of the formed pulses relative to the case of the exact resonance, while the maximum contrast is preserved.
