Titel
Comparison between bidirectional pumped YB-doped all-fiber single-mode amplifier and oscillator setup up to a power level of 5 kW
Abstract
We present and compare highly robust Yb-doped monolithic amplifier and -oscillator setups in 20/400 µm geometry achieving signal powers of 3.5 kW and 5 kW in a bidirectional pumping scheme while maintaining single mode beam quality of M 2 ~ 1.3.
