Long-short-wave optical solitons in uniaxial crystals

On the base of numerical experiments we demonstrate in that the process of THz generation in nonlinear optical crystal with uniaxial anisotropy can result to formation of (2+1)-dimensional half-cycle pulses at sufficiently long distance of propagation. We also observed the formation of nonsolitonic few-cycle THz pulses, which accompanies the formation of solitons.
