25 February 2008 Square-root law of turbulence-induced spectral broadening in Raman fiber lasers
Author Affiliations +
The output characteristics of the conventional one-stage Raman fiber laser are described theoretically by using the optical wave turbulence formalism. Simple analytical expressions describing RFL output power and its spectral shape are presented as well as square-root law for the output spectrum broadening law has been discovered. The indications of the turbulent-like spectral broadening in other types of CW fiber lasers and propagation phenomena in fibers are also discussed.
