In recent years, progress has been made in obtaining extremely short electromagnetic
pulses up to single-cycle and unipolar half-cycle pulses. For pulses with such a dependence …

The most typical way to optically control population of atomic and molecular systems is to
illuminate them with radiation, resonant to the relevant transitions. Here we consider a …

We study theoretically a possibility of creation and ultrafast control (erasing, spatial
frequency multiplication) of population density gratings in a multi-level resonant medium …

Electromagnetically induced gratings (EMIGs) of atomic populations are formed in the
resonant media at the interference of two or more overlapping monochromatic beams. They …

We study the optical response of a resonant medium possessing nonlinear coupling to an
external field driven by a few-cycle pump pulse sequence. We demonstrate the possibility of …

Our recent studies of methods for obtaining ultrashort light pulses and analysis of the impact
of ultrashort optical pulses on classical and quantum micro-objects with the identification of …

We propose a strikingly simple method to form approximately unipolar half-cycle optical
pulses via reflection of a single-cycle optical pulse from a thin flat metallic or dielectric layer …

Here, we show that light can bring itself to a complete standstill (self-stop) via self-interaction
mediated by the resonant nonlinearity in a fully homogeneous medium. An intense few-cycle …

We theoretically investigate the possibility of a passive mode-locking regime in a two-section
laser with an ultrashort cavity of the length around ten wavelengths of the medium resonant …

Creation, erasing and ultrafast control of population density gratings using few-cycle optical
pulses coherently interacting with resonant medium is discussed. In contrast to the …
