We demonstrate experimentally collisions between vector (Manakov-like) solitons that involve energy exchange at large collision angles, for which scalar pass through one another practically unaffected.
Atmospheric pressure plasma jets (APPJs) can be generated in capillary tubes flowing with pure helium and admixtures of oxygen into the helium.

We present the first experimental observation of (2+1) -dimensional multimode (composite) solitons. A single-hump component and a double-hump (dipole-type) are jointly self-trapped as composite soliton in biased photorefractive crystal.
We demonstrate experimentally second-harmonic generation in waveguides induced by photorefractive solitons and show that the conversion efficiency is improved considerably.

Such solitons become transversely stable only if correlation distance below specific threshold value. show this for instability coincides with value modulational instability.
