Abstract
Embodiments relate to a high power supercontinuum (SC) fiber optical source. The SC fiber optical source includes a prebroadening optical fiber that broadens the spectrum of a lower power intermediate optical signal before final amplification. The spectrum broadening creates spectral components which facilitate further spectrum broadening of amplified signal in final nonlinear stage, allowing to achive flatter and wider spectrum, and reduces nonlinear Stimulated Brillouin Scattering (SBS) that could damage SC fiber optical source components or limit the output power of the SC fiber optical source signal, thus enabling higher output power. After amplification in booster, passing at least part of broadened spectrum, the optical signal spectrum is further broadened by injecting the optical signal into a nonlinear stage to create a SC optical signal.
