Petahertz-bandwidth spectral combs from the amplified spontaneous emission of a collisional plasma-based x-ray laser
I. R. Khairulin, V. A. Antonov, I. D. Morskov +1
The possibility of generating spectral combs of petahertz bandwidth is demonstrated from amplified spontaneous emission (ASE) of a collisional plasma-based x-ray laser when its act…

Optimal conditions for the generation of moderate-order harmonics of a short-wave field by helium atoms
V. A. Antonov, I. R. Khairulin, M. Yu. Emelin +3
It is shown that under optimal conditions, the generation of the 3rd, 5th, 7th, and 9th harmonics of the short-wave, ultraviolet or vacuum ultraviolet, laser field by helium atoms…

Generation of Subfemtosecond Deep and Vacuum UV pulses via Two-Photon Rabi Oscillations in Alkali Atoms or Alkaline Earth Ions
I. R. Khairulin, A. A. Romanov, A. A. Silaev +2
A method is proposed for the formation of femto- and subfemtosecond pulses of the deep ultraviolet and vacuum ultraviolet radiation via generating the third harmonic of femtosecond…
