Dispersion-Managed Compact All-Fiber Ytterbium-Based Mamyshev Oscillator

Mamyshev oscillators have pushed the frontiers in output parameters of ultrafast fiber oscillators within recent years tremendously. Various configurations have been presented, reaching pulse energies as high as <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1.1 \mu \mathrm{J}$</tex> [1] and pulse durations as short as 17 fs [2]. Many of these setups compromise the stable, alignment free operation of monolithic fiber oscillators, since free-space components were used. Furthermore, pulses shorter than 100 fs are usually only achieved in cladding-pumped systems, alongside with high pulse energies, requiring several watts of pump power. Some setups even incorporate two gain sections, which increases the amount of needed components and complexity.
