We report a regime of the loose soliton bunch in an erbium-doped passively mode-locked fiber laser. In this state,every soliton bunch consists of multiple pulse
Loss is inevitable for the optical system due to the absorption of materials, scattering caused by the defects, and surface roughness. In quantum optical circui
Enhanced quantitative X-ray phase-contrast(QXPC) imaging is implemented with a Foucault knife-edge array filter(FKAF), which is a real differential spatial filt
The battle to extend the Bush-era tax cuts was politically divisive, and the process agonizingly prolonged. Yet the decision to continue the cuts—and throw in
