P levels. A numerical model developed to describe mechanisms involved in the conical emission generation processes indicates that the saturation observed is due to the opposite angular tuning of the near-infrared and yellow conical emission generated

We investigate numerically Optical Vortex Solitons (OVSs) with different topological charges ( m ) and show that they are characterised with soliton constants equal to the product of their topological charge and the soliton constant of unit OVS. The

An asymmetrically induced phase modulation resulting in an intensity-dependent spatial beam deflection and a subsequent spatial filtering have been used for all-optical pulse shaping and shortening. A compression factor of eight and controllable symm

The spatial dynamics of ring dark solitary waves is studied numerically in order to determine the appropriate initial conditions for an effective control of their transverse velocity. We show that the evolution of the solitary-wave parameters radius,

A method for ultrashort pulse-duration measurement is analysed both theoretically and experimentally. The approach is based on a time-resolved induced phase modulation of a probe beam-pulse in a two-colour Z-scan configuration. The experimental resul

Guiding of multiple signal beams in an induced all-optical cable is studied theoretically. A balance relation is derived for the interaction geometry and undistorted propagation of bright elliptical signal beams nested in a single ring dark soliton.

A four-frame technique for interferogram analysis is used to measure the transverse phase distribution of nonlinearly split 2D dark beams. Pairs of diametrical phase shifts within each ring are retrieved from the experiment. This result is one of the

We analyzed an alternative approach for guiding parallel signal beams nested between noninteracting fundamental bright spatial solitons. The numerical results show that stable signal-wave guiding without a cross-talk is obtainable even at small-inten

We report on the production of the NaHg molecule via resonant excitation of the sodium D-lines following energy-pooling collisions of laser-excited Na(3 2P) atoms. In addition to the chemiluminescence on the red NaHg(II1/2−X1/2) band system, we obs
