Single-Cavity Dual-Comb for field-deployable Spectroscopy

Laser light sources have become the tool of choice for precision spectroscopy experiments that target central questions in molecular physics and physical chemistry. Since the 2000s, optical frequency combs (OFCs) in particular have emerged as a very attractive laser light source combining the large spectral bandwidths previously only available from thermal sources with the frequency stability and brightness of continuous-wave lasers. To fully benefit from the properties of OFCs in spectroscopy experiments, the comb lines need to be resolved by appropriate means.

In this project, you will work on a novel approach of dual-comb spectroscopy based on a single laser resonator. The single-cavity approach offers the critical advantage that both OFCs share common noise, negating the need for complex stabilization schemes between the two OFC, hence paving the way for out-of-lab applications. You will convert the wavelength into the mid-IR spectral region and demonstrate a reliable fiber-based dual-comb spectrometer for spectroscopy on trace gases.

This experimental PhD position is available within the framework of the FWF standalone
project "Single-Cavity Dual-Comb Laser." More information can be found here.

The successful candidate will be part of a vibrant, active, and international team of researchers who work at the scientific forefront in laser physics and spectroscopy.

He/she will also be integrated into the Vienna Doctoral School in Physics (VDSP). The VDSP provides a comprehensive supporting infrastructure to all PhD students of the Faculty of Physics, which will offer you additional benefits throughout your PhD studies. These benefits include access to a mobility fellowship, conference travel grants, winter or summer schools, personal mentors besides your direct supervisor, career coaching days, and excursions.

If you are interested in this offer and hold /will be holding a Master's degree in Physics, Electrical Engineering, or a similar subject, then please don't hesitate to contact me via email at or give me a call under +43-1-4277-73806. I will continuously review applications and close this offer once a suitable candidate is found.
