Three Multiple-Pulse Operation States of an All-Normal-Dispersion Dissipative Soliton Fiber Laser

open access: yesInternational Journal of Optics, 2014
Multiple-pulse operation states of an all-normal-dispersion Yb-doped double-clad dissipative soliton fiber laser are investigated in this paper. The proposed laser can deliver harmonic mode-locked pulses, bound states of dissipative solitons, and dual ...

Double ionization in a one-cycle laser pulse

open access: yesOptics Express, 2000
The time-dependent Schrodinger equation is solved for a 1Dx1D two-electron model helium atom subject to a low-frequency short, intense laser pulse. A half-cycle pulse leads to strong single but no double ionization. A full-cycle pulse leads to double ionization which begins precisely at the classical return time for the first ejected electron.

Compact high-energy Q-switched cladding-pumped fiber laser with a tuning range over 40nm

open access: yes, 1999
We describe a compact Q-switched diode pumped double-clad ytterbium-doped fiber laser. The fiber laser was bidirectionally pumped by two laser diodes (2W of output power each) via two side-injecting pump-couplers.
