We present an all-polarization-maintaining mode-locked fiber laser based on a nonlinear
amplifying loop mirror utilizing a 3× 3 coupler. A pump laser diode placed outside the cavity …

A femtosecond all-PM-fiber Mamyshev oscillator (MO) at 920 nm is presented. It is based on
a neodymium-doped fiber with a W-type index profile that effectively suppresses the …

Ultrafast fiber oscillators based on loop mirror saturable absorbers often suffer from a
problematic self-starting mode-locking operation. It is usually necessary to provide an …

We demonstrate an all-fiber monolithic laser source from a gain-managed nonlinear (GMN)
fiber amplifier with a CFBG-based pre-compressor that generates high-contrast pulses with …

A cost-effective fiber laser architecture is introduced in which the output seed pulse is
stretched and then returned in the oscillator for an additional single-pass amplification …

In this Letter, we present an experimental demonstration of an all-fiber ring Mamyshev
oscillator (MO) that delivers a 300? mW optical power at a repetition rate of 45? MHz …

Nonlinear spectral broadening based on self-phase modulation (SPM) is essential for
achieving Mamyshev mode-locking. Changes in pulse shape due to dispersion, which …
