Generation of 9 W, 4 kHz linewidth 13C2H2 frequency-stabilized fiber laser output with core pumped erbium-doped amplifier

摘要

We demonstrate a record-high output power of 9 W and an ultranarrow linewidth of 4 kHz by combining a 13C2H2 frequency-stabilized fiber laser, a core-pumped erbium-doped fiber amplifier, and a cascaded-Raman 1480-nm fiber-laser pumping source.
