Resumen: The authors present here an attainable fiber supercontinuum source with competitive characteristics in the near infrared range. The proposed system is based on a highly nonlinear silica fiber, with nominal zero-dispersion wavelength at 1550 nm. A mode-locked fiber laser was used as the seed. The pump wavelength was shifted to match the zero-dispersion wavelength of the nonlinear fiber, achieving a better performance of the spectral emission. The supercontinuum emission was characterized between 1100 nm and 2300 nm, showing a flat and wide spectrum with a conversion efficiency over 80%. The set-up consists only in silica fiber and can be considered, therefore, as a cost-effective alternative for supercontinuum generation in the near infrared range, which can be easily implemented in any photonics laboratory, where commercial amplifiers are usual devices.
