Optical Frequency Comb Spectroscopy 

Dr. Aleksandra Foltynowicz 



Department of Physics 

Umeå University, Sweden E-mail: aleksandra.foltynowicz at physics.umu.se 



Optical frequency combs are produced by femtosecond mode-locked lasers, whose spectrum consists of a series of equidistant narrow lines spanning tens or hundreds of terahertz. The unique combination of wide optical bandwidth and high spectral resolution has opened up exciting new possibilities in spectroscopy. Spectroscopy performed with optical frequency combs is equivalent to a simultaneous measurement with thousands of narrow synchronized laser lines, and combines the high resolution and sensitivity of continuous wave laser spectroscopy with broad spectral coverage. Optical frequency comb spectroscopy has the potential to become the ultimate tool for trace gas detection since it allows highly sensitive simultaneous detection of many molecular species in short acquisition times. 

I will introduce the basics of optical frequency comb spectroscopy and give examples of applications of the technique. I will describe the system we developed in our group, based on a near-infrared Er:fiber frequency comb, an enhancement cavity, and a Fourier transform spectrometer, and present the first results of measurements in a combustion environment.
