We show that a field emission tip electron source that is triggered with a femtosecond laser pulse can generate electron pulses shorter than the laser pulse duration (100 fs).. The emission process is sensitive to a power law of the laser intensity, which supports an emission mechanism based on multiphoton absorption followed by over-the-barrier ..
Electron beams are powerful tools with applications ranging from treating cancer to recording ultrafast microscopic movies.. The temporal and spatial resolution of the latter is li
FIG.. 1.. Experimental setup.. The laser is focused onto the diamondcoated tungsten tip with an off-axis parabolic mirror (OAP).. The inset shows a transmission electron micrograph of the nanodiamondcoated tungsten tip.. A voltage below the DC field emission threshold is applied between tip and microchannel plate (MCP) to accelerate electrons towards the MCP.. See text for details.. - "Femtosecond ..
