“…It is interesting that contribution of this additional term is of resonant nature and has no saturation in dependence on pump wave intensity Ω. It repeats recently obtained regularity for the parametric down conversion process [13]. This out of dipole approximation contribution appears attractive in far IR or longer wavelength ranges of radiation.…”

We present a new method for generating a regular train of ultrashort optical pulses in a prepared two-level medium. The train develops from incident monochromatic probe radiation travelling in a medium of atoms, which are in a quantum mechanical superposition of dressed internal states. In the frame of linear theory for the probe radiation, the energy of individual pulses is an exponentially growing function of atom density and of interaction cross section. Pulse repetition rate is determined by the pump field's generalized Rabi frequency and can be around 1 THz and greater.We also show that the terms, extra to the dipole approximation, endow the gas by a new property: non-saturating dependence of refractive index on dressing monochromatic field intensity. Contribution of these nonsaturating terms can be compatible with the main dipole approximation term contribution in the wavelength region of about ten micrometers (the range of CO 2 laser) or larger.

“…Later we will refer to this scheme as QS (quantum superposition) generator. Another interesting result based on superposition principle was discussed in [15]. We showed that the phase matching condition for the parametric down conversion process is split into three conditions (it reminds one of Mollow's splitting in the case of one-photon luminescence).…”

“…In general this process can be accompanied by pulse amplification. It may be interesting, in addition, that the gas refractive index in comparison with earlier known results contains out of dipole approximation terms of resonant nature which have no saturation in dependence on pump wave intensity [15].…”
