Peculiarities for space-time structure of powerful electromagnetic pulses formed with thin plasma layers
Shaping of femtosecond laser pulses of petawatt level with plasma layers is analyzed. It is shown that, for electron density exceeding the critical density by several times, it is possible to generate asymmetrical pulse with the amplitude of the first half-cycle, which is practically equal to the maximal amplitude of the pulse. These pulses are necessary for effective generation of relativistic electron mirrors. Spatial structure of the pulse transmitted through a plasma layer is corresponding qualitatively to the field structure after diffraction of the same initial pulse on a slit. It is shown that supergaussian pulses are more preferable for shaping with respect to pulses of Gaussian shape because the output pulse in this case have sharper fronts and more homogeneous distribution of the field in transverse direction.
