Precision spectroscopy is the measurement of the spectrum of atoms and molecules using lasers. American physicist John Lewis “Jan” Hall (born 1934) and German physicist Theodor Wolfgang Hänsch (born 1941) were co-developers of the “frequency comb technique,” a method for fine-tuning laser outputs to measure spectrum frequencies with great precision. Hall and Hansch shared one half of the 2005 Nobel Prize in Physics “for contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique,” which is this work.
