Starting Dynamics of a Fully Electronically Controlled Linear Mamyshev Oscillator
Yi-Hao Chen, Pavel Sidorenko, Frank Wise
We start an environmentally-stable linear Mamyshev oscillator with electronically-controlled modulated pump and a moving filter. It delivers a 21-nJ pulse that becomes 65 fs in dur…
Deep learning reconstruction of ultrashort pulses from 2D spatial intensity patterns recorded by an all-in-line system in a single-shot
Ron Ziv, Alex Dikopoltsev, Tom Zahavy +4
We propose a simple all-in-line single-shot scheme for diagnostics of ultrashort laser pulses, consisting of a multi-mode fiber, a nonlinear crystal and a CCD camera. The system re…
Mechanisms of Spatiotemporal Mode-Locking
Logan G. Wright, Pavel Sidorenko, Hamed Pourbeyram +6
Mode-locking is a process in which different modes of an optical resonator establish, through nonlinear interactions, stable synchronization. This self-organization underlies light…
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…
