Paper Abstract

In the present work, we fabricated Yb-doped hybrid fiber, where unwanted mode suppression was achieved due to selective mode amplification technique. An asymptotically single-mode propagation regime of the realized hybrid fiber was observed in the amplifier scheme even for the case when significant amount of undesirable modes was excited at the fiber input. Measured dispersion of the hybrid fiber at wavelength of 1030 nm was about 70 psec/(nmkm). The realized hybrid fiber was used as nonlinear compressor in all-fiber amplifier scheme. As a seed source we used a commercially available chirped pulse laser (λ~ 1030 nm, a spectrum width was 11 nm and a pulse repetition rate was 42 MHz, pulse duration was adjusted to be of 1 psec by diffraction gratings established on the output of the seed laser). In our experiment to guarantee shorter optimal active fiber length we chose wavelength stabilized pump source at 976 nm. Thus the record high peak power (~10 kW) for all-fiber femtosecond Yb-doped laser schemes was achieved.
