Abstract :
In this paper, new spectral components formation under filamentation of pre-collimated laser beam in molecular gases is reported. These components arose at the red and blue sides of the initial spectrum and were attributed to the generation of vibrational Raman "spectral solitons" and their cascaded four-wave mixing.
