We develop an all polarization-maintaining (PM) 920 nm Nd-doped fiber amplifier delivering
a train of pulses with∼ 0.53 W average power and sub-50 fs duration. The sub-50 fs pulse …

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 …

We present a comprehensive study of dispersion managed ultrashort-pulse generation in
Nd-doped polarization maintaining all-fiber laser at a 920 nm wavelength. We implement a …

We demonstrate a femtosecond all-polarization-maintaining Nd fiber laser working at 920
nm mode locked by a biased non-linear loop mirror. The broadest spectral width of the pulse …

Ultrashort pulses at 920 nm are a highly desired light source in two-photon microscopy for
the efficient excitation of green fluorescence protein. Although Nd3+-doped fibers have been …

The advent of optical metrology applications has necessitated the development of compact,
reliable, and cost-effective picosecond lasers operating around 900 nm, specifically catering …

We demonstrate a watt-level femtosecond fiber laser system at 0.9 µm with a repetition rate
