Pulse duration and energy scaling of femtosecond all-normal dispersion fiber oscillators

Abstract

We investigate the scaling properties of mode-locked all-normal dispersion fiber oscillators in terms of output pulse energy and compressed pulse duration. Experimental results are achieved by stepwise variation of the resonator dispersion, total fiber length, and the spectral filter bandwidth. Adjustment of these parameters enables pulse duration scaling down to 31 fs and increase of output pulse energy up to 84 nJ.

Coherent Raman Scattering Microscopy in Biology and Medicine

“…Early on, the major obstacle to nonlinear microscopy using fiber lasers was the insufficient output of pulse energy, which ultimately required the involvement of amplification systems that increased the system’s complexity. This problem was solved by the advancement of dissipative-soliton fiber lasers, which can output tens of nanojoule pulses with a pulse width of hundreds of femtoseconds, thus reaching the energy level of solid-state crystal lasers (154–156). The corresponding peak power is strong enough for nonlinear microscopy (157, 158).…”

Enhanced spectral breathing for sub-25 fs pulse generation in a Yb-fiber laser

“…To date, laser pulses as short as ∼30 fs can be routinely obtained from dispersion-managed soliton Yb fiber lasers operating in the vicinity of zero cavity dispersion [4,5]. Similar performance can be achieved from all normal dispersion fiber lasers by downscaling of active fiber length [6]. In both cases, the further pulse duration shortening is restricted by the amplifier bandwidth of Yb-doped fiber.…”

Optimal design of higher energy dissipative-soliton fiber lasers

“…In 2012, Chichkov et al have experimentally investigated the scaling properties of an ANDi laser. Using ytterbium-doped double-clad fiber as the gain medium, and by stepwise variation of the resonator dispersion, total fiber length, and the spectral filter bandwidth, they have obtained pulse with the pulse energy up to 84 nJ [28].
