Abstract

We report on a self-starting Yb-doped fiber laser based on all-normal dispersion polarization maintaining (PM) fiber components. The cavity is mode-locked using a nonlinear optical fiber loop mirror (NOLM) that provides a stable generation of linearly polarized, linearly chirped picosecond pulses. The achieved pulse energy is 5.9 nJ. External grating-pair compression down to 265 fs has been demonstrated.
