Angular distribution of electron emission from ultrafast nanotip sources
Jonathan M. Geller, Michael J. Faulkner, Iona K. Binnie +1
We investigate the angular distribution of ultrafast laser-induced electron emission from a tungsten nanotip in the multiphoton regime. A theoretical model allows precise determina…
Ultrafast time resolved photo-electric emission
Thomas Juffmann, Brannon B. Klopfer, Gunnar E. Skulason +4
The emission times of laser-triggered electrons from a sharp tungsten tip are directly characterized under ultrafast, near-infrared laser excitation at Keldysh parameters $6.6< γ<…
Ultrafast laser-triggered emission from hafnium carbide tips
Catherine Kealhofer, Seth M. Foreman, Stefan Gerlich +1
Electron emission from hafnium carbide (HfC) field emission tips induced by a sub-10 fs, 150 MHz repetition rate Ti:sapphire laser is studied. Two-photon emission is observed at lo…
A spatially and temporally localized sub-laser-cycle electron source
Peter Hommelhoff, Catherine Kealhofer, Mark A. Kasevich
We present an experimental and numerical study of electron emission from a sharp tungsten tip triggered by sub-8 femtosecond low power laser pulses. This process is non-linear in t…
