瑞典优密欧大学实验物理学博士后职位

The Optical Frequency Comb Spectroscopy Group works with the development and applications of cavity-enhanced optical frequency comb spectroscopy (CE-OFCS) for broadband ultrasensitive detection of molecular species in the gas phase. We have a fully operating CE-OFCS system based on an Er:fiber femtosecond laser and a fast-scanning Fourier transform spectrometer. We have recently used this system to demonstrate, for the first time with this technique, detection of broadband high-temperature water spectra in a flame. Moreover, we have developed a new sensitive detection method, which we termed noise-immune cavity-enhanced optical frequency comb spectroscopy (NICE-OFCS); the technique combines frequency modulation and cavity enhancement in a manner similar to NICE-OHMS in cw spectroscopy, and allows achieving immunity to laser frequency-to-amplitude noise conversion over the broad spectral bandwidth of the optical comb. In parallel, we are developing a mid-infrared CE-OFCS system, based on a Tm:fiber-laser-pumped optical parametric oscillator for applications in combustion analysis and environmental research.

We are now seeking a postdoctoral researcher to work on the project aimed at applications of CE-OFCS in combustion analysis and at further development of the NICE-OFCS technique. The appointment is for two years full time starting in the fall 2014.

The successful candidate should hold a PhD degree in experimental physics (or equivalent) obtained less than three years ago. The candidate should have experience in the fields of laser spectroscopy, optics, electronics, and trace gas detection. The applicant should be highly motivated and have the ability to work independently as well as a part of the research group. The candidate should be fluent in both oral and written English.

The application should include a motivation letter describing previous research experience, a CV with a list of publications, copies of relevant exam certificates and publications, and contact information of two referees who should be prepared to write a letter of recommendation. Documents should either be sent in hard-copy form (2 copies), or electronically in MS Word or PDF format, to the address below.
