High-energy pulses from an Yb-doped fiber Mamyshev oscillator by the use of a few-mode amplification fiber
9th EPS-QEOD Europhoton Virtual Conference
30. August - 04. September
We use a standard step-index few-mode Yb-doped gain fiber with a core diameter of 20µm in a Mamyshev oscillator to generate pulse energies of more than 500nJ directly from the laser oscillator. The pulses can be compressed to sub-100fs with an efficiency of 85\%.
