264 W output power at 1585 nm in ErYb codoped fiber laser using in-band pumping
We demonstrate a high-power cladding-pumped Er–Yb codoped fiber laser with 74% efficiency. A pump-limited output power of 264 W is obtained using in-band pumping at 1535 nm. We compare the efficiency of 1480 and 1535 nm pumping through numerical simulations and experimental measurements.
