Department of Physics is looking for a postdoctoral researcher to participate in a project aimed at broadband precision measurements of high-resolution molecular spectra using a mid-infrared optical frequency comb Fourier transform spectrometer. Application deadline is Oct 10, 2017.

Project Description
The Optical Frequency Comb Spectroscopy Group works with development and applications of optical frequency comb spectroscopy for broadband precision measurements and sensitive detection of molecular species in gas phase. We are now seeking a postdoctoral researcher interested in using optical frequency comb spectroscopy for precision measurements of molecular spectra. The aim of the project is to measure high-resolution mid-infrared spectra of molecules using comb-based Fourier transform spectrometry and determine the absorption line parameters in a wide range of pressures and temperatures. The spectrometer is based on a doubly-resonant optical parametric oscillator pumped by a Tm:fiber femtosecond laser, a fast-scanning Fourier transform spectrometer and a multipass cell (Opt. Lett. 41, 2541, 2016). The project involves 1) optimization of the existing spectrometer for high resolution measurements using the method described in Phys. Rev. A 93, 021802(R), 2016, and JQSRT 204, 63-73 (2017), 2) implementation of an enhancement cavity to increase the sensitivity, and 3) systematic measurements of molecular spectra and retrieval of line parameters using line shapes beyond the Voigt profile.

The project is for two years starting in Jan 2018, the exact date can be negotiated. The stipend is financed by the Knut and Alice Wallenberg Foundation and it amounts to 342 000 SEK per year (the stipend is tax-free).

Competence requirements
The successful candidate should hold a PhD degree or a foreign degree that is deemed equivalent to a PhD degree in experimental physics (or equivalent subject). Priority should be given to candidates who have completed their doctoral degree no more than three years before the application deadline unless special circumstances exist. The applicant must have previous experience in laser-based molecular spectroscopy and a strong interest in both technical development and theoretical modelling of the signals. The applicant should be highly motivated and have the ability to do resarch independently as well as a part of the research group. The candidate must be fluent in both oral and written English.

Application
The application should include:

  1. A motivation letter describing previous research experience relevant to the project (max 2 pages).
  2. Curriculum vitae with a list of publications.
  3. Copy of the PhD thesis.
  4. Copies of two most relevant publications.
  5. Copies of relevant exam certificates.
  6. A list of university courses with grades.
  7. Contact information of three reference persons.

Information
For more information contact Dr. Aleksandra Foltynowicz-Matyba, aleksandra.foltynowicz@umu.se

Your complete application, marked with reference number Dnr FS 2.1.6-1536-17, should be sent in a pdf-document to medel@diarie.umu.se (state the reference number as subject) on Oct 10, 2017 at the latest.
