PostDoc Laser Spectroscopy (m/w)


FSU Jena

Veröffentlicht am: 30.07.2018

We are looking for a postdoc who joins our team: since February 2017, we have been working on the further advancement of dual comb spectroscopy towards the XUV spectral region at the Abbe Center of Photonics of the Institute of Applied Physics in Jena.

By overlapping two frequency combs with slightly different repetition rates, dual comb spectroscopy enables, similarly to Fourier transform spectroscopy, the measurement of broadband absorption spectra, however with million times shorter acquisition times and unrivaled relative spectral resolutions of up to 10-9. This has been proven already in different spectral regions (NIR, MIR, VIS, THz). However, the high-energy part of the electromagnetic spectrum, the extreme ultraviolet (XUV), has so far been inaccessible to the innovative spectroscopic method due to the lack of appropriate laser sources. With the help of the high power fiber amplifiers developed in Jena in the recent years, dual comb spectroscopy is now being expanded into the XUV (6-100eV) at the Institute of Applied Physics. With this, investigations of the (highly) excited states in atoms and molecules with unprecedented spectral resolution up to a few μeV become possible.
