We demonstrate an all-fiber picosecond soliton laser with dispersion management performed by a chirped Bragg grating that generates ~1.6 ps pulses representing the shortest pulsewidth reported to date using this technology. The large anomalous dispersion provided by the grating allows building of a long-length cavity laser with an extremely low fundamental repetition rate of 2.6 MHz. This source allows us to use an original approach for producing energetic pulses that after boosting in a medium power core-pumped amplifier produce an octave-spanning supercontinuum radiation in a nonlinear photonic crystal fiber.
