Transformation of the field of an intense ultrashort pulse in a Raman-active medium
Belenov E. M., Isakov V. A., Kanavin A. P., Smetanin I. V.
The propagation of an intense femtosecond pulse in a Raman-active medium is analyzed. The field of an intense light wave undergoes a substantial transformation as the wave propagates through the medium. The nature of this transformation can change over time scales comparable to the period of the optical oscillations. The transformed spectrum of the light is found for an optically thin medium. © 1994 American Institute of Physics.
