Welcome to the Optical Frequency Comb Spectroscopy Laboratory at Umeå University, Sweden
Optical frequency combs are produced by femtosecond mode-locked lasers, whose optical spectrum consists of a series of equidistant narrow lines spanning tens or hundreds of nanometers. 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. Optical frequency comb spectroscopy is becoming the ultimate tool for precision spectroscopy and trace gas detection since it allows precise measurement of entire molecular bands and highly sensitive simultaneous detection of many molecular species in short acquisition times.
Our group works with development and applications of Optical Frequency Comb Spectroscopy for broadband precision measurements of entire molecular absorption bands and for multispecies trace gas detection.
