Broadband diode-pumped ytterbium-doped fiber amplifier with 34 dBm output power
Broadband diode-pumped ytterbium-doped fiber amplifier with 34 dBm output power
We investigate a high-power diode-pumped double-clad ytterbium-doped fiber amplifier with 34 dBm average output power and 1050 - 1095 nm bandwidth. A multi-diode concentrator pumps the amplifier at 980 nm, with ~6 W of power launched into the inner cladding. Besides cw-signals, we amplify pulses from a mode-locked laser to 1 kW of peak power with only minor nonlinear distortions as well as pulses from a Q-switched laser to 50µJ of energy. Reflections and back-scatter limit the gain of the amplifier to 40 dB for a pump power of 2.5 W. For higher pump-powers than this, the amplifier started to self-Q-switch. The results are important for the development of cladding-pumped high-power fiber amplifiers.

Abstract
We investigate a high-power diode-pumped double-clad ytterbium-doped fiber amplifier with 34 dBm average output power and 1050 - 1095 nm bandwidth. A multi-diode concentrator pumps the amplifier at 980 nm, with ~6 W of power launched into the inner cladding. Besides cw-signals, we amplify pulses from a mode-locked laser to 1 kW of peak power with only minor nonlinear distortions as well as pulses from a Q-switched laser to 50µJ of energy. Reflections and back-scatter limit the gain of the amplifier to 40 dB for a pump power of 2.5 W. For higher pump-powers than this, the amplifier started to self-Q-switch. The results are important for the development of cladding-pumped high-power fiber amplifiers.
