Ultrafast Physics of Light and Matter

Prof. Philip Russell Prof. Philip Russell (MPL, Erlangen) Generation of ultrafast laser pulses with non-linear processes in matter Photonic crystal fibres (PCFs), through their ability to exquisitely control the flow of light, continue to yield novel optical properties and applications. An example is twisted PCF, which creates optical vortices that carry orbital angular momentum, as well as providing an elegant means of providing circular birefringence and dichroism, most recently in hollow-core PCF. Intense interactions between light and sound in solid-core PCF enable stable all-optical mode-locking of fibre lasers at a high harmonic (a few GHz) of the round-trip frequency. Single-ring hollow-core PCF, comprising a ring of thin-walled capillaries surrounding a central hollow core, guides light over an extremely wide frequency range and, through pressure-adjustable dispersion, provides a simple means of compressing pulses down to durations as short as a single optical cycle, as well as underpinning a range of unique and extremely bright sources of tuneable deep and vacuum ultraviolet light. During the talk, a selection of recent results from work carried out at MPL will be presented.
Prof. Peter Hommelhoff Prof. Peter Hommelhoff (FAU, Erlangen) Strong field physics in atoms and solids In strongfield physics, matter is exposed to light fields that are so strong that they are comparable in field strengths to the fields holding matter together. This has led to entirely new effects, such as the efficient generation of high harmonics of laser light, the generation of attosecond light pulses, or ultrafast electron diffraction of atoms and molecules with the electron taken from the sample under study. While strongfield physics in atoms and molecules has been investigated for the last 30 years, strongfield physics in solids is younger. Various new effects based on the interplay of intraband and interband effects, such as the ultrafast current generation in graphene, have been observed. This talk will cover the fundamental concepts of strongfield physics as well as the current state of research.
Prof. Robert L. Byer Prof. Robert L. Byer (Stanford Univ.) Ultrafast manipulation of free electrons with light In 2015 the Moore Foundation accepted a proposal to fund an accelerator science program with the goal of demonstrating a laser driven accelerator on a chip. To date the international collaboration has demonstrated greater than 850MeV/meter gradient in a fused silica grating structure and has demonstrated the first accelerators based on silicon. The ACHIP collaboration is making progress toward a 100MHz repetition rate accelerator with attosecond electron bunches to enable applications to electron imaging and diffraction and to medicine. Progress in the ACHIP program can be found at the website


Der diesjährige Studenten-Workshop widmet sich voll und ganz dem aktuellen Forschungsfeld der Ultrakurzzeit-Physik auf der Femto- bis Attosekundenskala. Die Teilnehmer werden von den physikalischen Grundlagen über etablierte Techniken bis zur aktuellen Forschung geleitet. Dadurch wird ein Einblick in dieses spannende und zukunftsträchtige Forschungsgebiet gegeben - und das innerhalb eines Tages.


Wir freuen uns sehr, dass wir internationale Größen dieses Forschungsbereichs als Sprecher gewinnen konnten. Daher werden die Vorlesungen auf English gehalten, es dürfen allerdings jederzeit Fragen auf Deutsch gestellt werden.
