The Fritz-Haber-Institut (FHI) in Berlin-Dahlem is one of the most renowned institutes within the Max Planck Society (MPG), Germany's organization for basic research. At the FHI, scientists from all over the world are engaged in fundamental studies in the field of chemical physics at interfaces and surfaces, catalysis research and molecular physics.

Environment: The project is a collaborative effort between the Department of Physical Chemistry (Prof. Martin Wolf) at the Fritz-Haber-Institute of the Max Planck Society in Berlin and the Attoscience and Ultrafast Optics Group (Prof. Jens Biegert) at ICFO in Barcelona, The project will be realized at FHI Berlin, but part of the time will be spent at ICFO Barcelona. Both environments are highly international and the experimental environment includes several unique few-cycle intense light sources, attosecond soft x-ray beamline for x-ray spectroscopy, and a reaction microscope for single electron imaging of molecular structure. We are embedded in several prominent national, European and international networks and collaborations, which ensures a vibrant and stimulating research environment and prominent exposure.

PhD Student Position: Extreme mid-infrared photonics

Project description: The Ph.D. thesis aims at the realization of a unique source of intense mid-IR pulses for the generation of intense attosecond soft-X-ray radiation. The core of the projects deals with designing and realizing a unique and cutting-edge light source of ultrashort pulses in the mid-IR wavelength range together with advanced electric-field-resolving diagnostics techniques. The specific research area is very competitive, and we expect ample opportunities for publications and large visibility within the community. The work deals with different laser technologies, including high-power lasers, nonlinear crystals, parametric amplification schemes, carrier-envelope phase control and simulations. Within the PhD project, the candidate will be involved in each stage of the project from planning to acquisition of parts, assembling and testing. The work load will be shared with another PhD student in collaboration with a post-doctoral researcher. The experience that the candidate will gain in this step will provide him/her with a unique professional profile that will guarantee a smooth entrance into the job market, either in industry or academia. The success of this project will have significance across Attoscience, Atomic/Molecular/Solid State Physics and Ultrafast X-ray Science.

Position: The PhD position is fully funded and the employment is at FHI Berlin (2/3 of Pay Group 13 of TVöD, for probably 4 years). The position is available immediately and we will provide a stimulating environment to perform research on the cutting edge of both science and technology.
