Electron emission from surfaces induced by HCI and lasers

Electron emission from surfaces due to interaction with charged particles and electromagnetic fields is a topic of research for over 100 years. In the past decade new developments in the production of ultrashort laser pulses (τ < 10 fs at a wavelength of λ ≈ 750 nm) and of slow highly charged ions (HCI) have rendered these interactions to be remarkably similar. The description of electron emission in HCI-surface interactions can therefore be transcribed to model and understand photoemission from surfaces interacting with ultrashort laser pulses. Examples will be presented for two model systems.
