We report what to our knowledge are the first observations of an increase in the on-axis
intensity of an intense cw on-resonance beam resulting from nonlinear absorption and …

A single pass of an intense cw light beam through a strongly absorbing medium can be
characterized by two parameters, the input on-axis intensity normalized to the saturation …

We describe a conical emission process that occurs when two beams of near-resonant light
intersect as they pass through sodium vapor. The light is emitted on the surface of a circular …

Continuous-wave (cw) off-resonance rings and cw on-resonance enhancement (CORE) are
observed as a result of an optical beam propagating through sodium vapor. They are …

Analytical and numerical methods are used to study the transverse reshaping that occurs
when ultrashort optical pulses propagate through media resonant to the pulse carrier …

We show that the shape of a nearly resonant cw laser beam transmitted through a sodium
cell is modified when a buffer gas is introduced in the cell. Depending on the sign of the …

This paper deals with the strongly nonlinear regime of the atom and field interaction which
arises for both high cw input intensities and large absorption. The intensity of the light inside …

We suggest an improved numerical algorithm for nonlinear paraxial optics that makes use of
the modified quasi-fast-Fourier–Bessel transform and the special high-harmonic correction …

Continuous-wave self-deflection of an asymmetrical laser beam, with a deflection angle up
to eight diffraction widths, and strong attenuation of the on-axis radiation were achieved in a …
