Further power scaling of narrow-linewidth fiber lasers is critical for beam combining. Using all-solid photonic bandgap fibers with large effective mode areas and strong higher-order-mode suppression is an interesting approach. Previously, we demonst

Using an ytterbium-doped fiber with a 50 μm core and 0.028 NA, a pulse energy of 4.8 mJ was achieved directly from a single-mode Q-switched fiber laser. The repetition rate was 10 kHz and the average power was 48.4 W. The slope efficiencies with reg

We have demonstrated a new record of 302W single-mode power from an Er/Yb co-doped fiber master oscillator power amplifier (MOPA) with a record optical efficiency of 56%. This single-mode power is a new record for any lasers in this wavelength range.

Conventional models of Er/Yb co-doped fibers assume all ytterbium ions are equally involved in the energy transfer with erbium ions, governed by a singular transfer rate. This would predict output power clamping once ytterbium parasitic lasing starts

We demonstrate a double-cladding Er/Yb fiber MOPA counter-pumped by 915nm pump diode, which produces a record high output of 302W diffraction-limited power at 1562nm with an optical efficiency of 56% and average M2 ~1.04.

There have been several demonstrations of single-frequency single-mode ytterbium-doped fiber lasers operating at a few hundred watts of power. A narrow spectral linewidth of these lasers is critical for many applications but has never been properly m

Diffraction-limited 976nm lasers can be used to core-pump ultrafast fiber lasers to overcome nonlinearities with significantly shortened fiber lengths or to pump ultrafast solid-state lasers for much improved beam quality. In order to make Yb fiber l

There is still significant need for power scaling of fiber lasers. Large-mode-area fibers are a key for the mitigation of optical nonlinearities. In recent years, mode instability has shown itself to be an additional significant limiting factor for s
