Mode-locked fiber laser、High power

In this work, we demonstrate a chirp-managed Yb-doped fiber laser operating in a net positive dispersion regime using a long segment of single-mode fiber and weak grating-based dispersion compensation. Despite the simple architecture, the laser generates 1.1 ps pulses with 14 nJ pulse energy at 78 MHz, resulting in 1.1 W average output power.
