At MBI, Barth conducts basic research in high-field and attosecond physics. Already in his doctoral thesis, he discovered how electrons can be forced onto an annular path by laser pulses, creating extremely strong magnetic fields inside. According to his calculations, they far surpass the strongest permanent magnetic field of nearly 100 Tesla produced in the laboratory. At MBI, he continues this research to control electron motion through laser pulses. For his findings Barth was among others awarded the Carl Ramsauer Prize of the German Physical Society in Berlin.
Ingo Barth is also committed to the further development of sign language and the establishment of a "European DeafUniversity".
