We report on the generation of self-similar highly-stable femtosecond pulses from a side-pumped ytterbium-doped double-clad fiber laser. Positively-chirped parabolic pulses with 6.4 ps duration and more than 3.2 nJ energy are obtained. These pulses are extra-cavity compressed to 140 fs. The noise measurements using radio-frequency analysis show that this regime of emission ensures low-noise operation with less than 0.05 % amplitude fluctuations.
