Nonlinear ultrafast fiber amplifiers beyond the gain-narrowing limit
Pavel Sidorenko, Walter Fu, Frank Wise
Ultrafast lasers are becoming increasingly widespread in science and industry alike. Fiber-based ultrafast laser sources are especially attractive because of their compactness, ali…
Multi-megawatt, self-seeded Mamyshev oscillator
Pavel Sidorenko, Walter Fu, Logan G Wright +1
We demonstrate a fiber oscillator that achieves 3 MW peak power, is easily started and is environmentally stable. The Mamyshev oscillator delivers 190-nJ pulses that can be compres…
High-power femtosecond pulses without a modelocked laser
Walter Fu, Logan G. Wright, Frank W. Wise
We demonstrate a fiber system which amplifies and compresses pulses from a gain-switched diode. A Mamyshev regenerator shortens the pulses and improves their coherence, enabling su…
Limits of Femtosecond Fiber Amplification by Parabolic Pre-Shaping
Walter Fu, Yuxing Tang, Timothy S. McComb +2
We explore parabolic pre-shaping as a means of generating and amplifying ultrashort pulses. We develop a theoretical framework for modeling the technique and use its conclusions to…
