Аннотация: The problem of obtaining a single attosecond pulse using high-order harmonics generation is under consideration. A method for producing an exciting light pulse with a time dependent degree of ellipticity From one-frequency linearly polarized laser pulse by means of linear optics is suggested. The whole of the field generated by limited beam of this light in gas target is calculated in the far zone. For this calculations, we use an original method based on time approach of a theory of high-order harmonic generation. Suppressing the low-frequency part of the spectrum (i.e., extracting the high-frequency part) by pinholes is simulated. Contrasted and intense (focused) single attosecond soft X-ray pulses are calculated.
