Ohm Prize awardees 2018

Our former bachelor student Helene Müller and our former master student Jonas Heimerl were honoured with an Ohm Prize for their final theses at the graduation ceremony of the Department of Physics. This award for the best theses of the past year is presented “for the promotion of young scientists in the field of physics at the University of Erlangen-Nuremberg”.

In her bachelor thesis entitled “Spectral Broadening of Ytterbium-Femtosecond Laser Pulse in a Multiple-Glassplate-Setup”, Helene Müller investigated the spectral widening of laser pulses by means of successively arranged glass plates. In combination with glass cylinders, she received a spectral widening by a factor of seven for a ytterbium-doped femtosecond laser in the near infrared. A pulse compressor reduced the original pulse duration from 300 fs to the Fourier limited pulse duration of 39 fs.

Jonas Heimerl presents in his work “Probing of optical near-fields by photoemission measurements in a nanoscale two-tip junction under few-cycle laser pulse illumination in an STM-based setup” a scanning tunneling microscope with optical access under ambient conditions. The controlled nanometer-precise positioning of two sharp, opposing metal needles allowed the measurement of non-linear electron photoemission processes. This allowed conclusions to be drawn about optical near-fields that occur particularly strongly at the metal tip.

Congratulations to all awardees!
