Description

Laser Spectroscopy and Optical Combs Central elements of laser spectroscopy will be discussed, with particular emphasis on the optical comb generator. An optical comb generator which allows optical frequencies to be precisely measured in terms of the cesium second is currently revolutionizing accurate laser spectroscopy. It plays a crucial role, for example, in extremely accurate hydrogen spectroscopy, to determine the important Rydberg constant and Lamb shifts. Helium spectroscopy to measure the fine structure constant from atomic fine structure will be discussed as an example.
