Tracing attosecond electron emission from a nanometric metal tip
Philip Dienstbier, Lennart Seiffert, Timo Paschen +4
Solids exposed to intense electric fields release electrons through tunnelling. This fundamental quantum process lies at the heart of various applications, ranging from high bright…
High-order above-threshold photoemission from nanotips controlled with two-color laser fields
Lennart Seiffert, Timo Paschen, Peter Hommelhoff +1
We investigate the process of phase-controlled high-order above-threshold photoemission from sharp metallic nanotips under bichromatic laser fields. Experimental photoelectron spec…
Two-color coherent control of femtosecond above-threshold photoemission from a tungsten nanotip
Michael Förster, Timo Paschen, Michael Krüger +6
We demonstrate coherent control of multiphoton and above-threshold photoemission from a single solid-state nanoemitter driven by a fundamental and a weak second harmonic laser puls…
Two-color coherent control in photoemission from gold needle tips
Philip Dienstbier, Timo Paschen, Peter Hommelhoff
We demonstrate coherent control of photoemission from a gold needle tip using a two-color laser field. The relative phase between a fundamental field and its second harmonic imprin…
Non-adiabatic ponderomotive effects in photoemission from nanotips in intense mid-infrared laser fields
Johannes Schötz, Sambit Mitra, Harald Fuest +10
Transient near-fields around metallic nanotips drive many applications, including the generation of ultrafast electron pulses and their use in electron microscopy. We have investig…
High Visibility in Two-Color Above-Threshold Photoemission from Tungsten Nanotips in a Coherent Control Scheme
Timo Paschen, Michael Förster, Michael Krüger +6
In this article we present coherent control of above-threshold photoemission from a tungsten nanotip achieving nearly perfect modulation. Depending on the pulse delay between funda…
