Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

Ultrafast lasers are becoming increasingly widespread in science and industry alike. Fiber-
based ultrafast laser sources are especially attractive because of their compactness …

Ensuring self-driven mode-locking and broadband wavelength tuneability in all-fibre-
integrated femtosecond laser sources enables a new level of their versatility and extends …

We demonstrate numerically and experimentally a gain-managed nonlinear amplifier with a
large mode area fiber. The amplifier delivers 1.2 µJ and sub-40 fs pulses with the spectrum …

Mamyshev oscillators can generate high-power femtosecond pulses, but starting a mode-
locked state has remained a major challenge due to the suppression of continuous-wave …

In this work, we show that the nonlinear evolution of femtosecond seed pulses with different
parameters (temporal and spectral shapes, repetition rate, pulse energy) in an Yb-fiber …

Two-photon excited fluorescence microscopy is a widely-employed imaging technique that
enables the noninvasive study of biological specimens in three dimensions with sub …

We demonstrate a pre-chirp managed Yb-doped fiber laser system that outputs 75 MHz, 130
W spectrally broadened pulses, which are compressed by a diffraction-grating pair to 60 fs …

Fundamental repetition rates of 3.1 GHz, 7.0 GHz, and 12.5 GHz in passively modelocked
Yb-doped fiber lasers are demonstrated. To the best of our knowledge, the fundamental …

A numerical model for amplification of ultrashort pulses with high repetition rates in fiber
amplifiers is presented. The pulse propagation is modeled by jointly solving the steady-state …
