A new method of laser frequency measurements of molecular spectral lines


Physicists from the Nicolaus Copernicus University (UMK) in Toruń have developed a new method of laser measurements of the frequency of molecular spectral lines. The research results that it can achieve are accurate on an unprecedented scale. You can read about them in an article that received the Editor’s pick in Optics Express.

“We presented a new measurement method, showing that it leads to more precise and reliable results than the methods that have so far been used in the same measurement context”, says Dr Katarzyna Bielska from the Department of Atomic, Molecular and Optical Physics of the Nicolaus Copernicus University.

The method presented to Prof. Daniel Lisak and Dr Katarzyna Bielska from the Institute of Physics of the Nicolaus Copernicus University can be used for measuring the energy of molecular transitions requiring the highest accuracy with the use of lasers with lower power than in traditional absorption measurements.
