https://doi.org/10.1007/978-3-658-37926-1d sources are characterised and described. The subjects discussed include UV and VUV lasers, synchrotron and undulator emission, harmonic generation, and free electron lasers of the Compton and Raman scattering types, as well as their associated equipment. Applications of free electron lasers are briefly considered.

Sebastian Gawron,Sebastian Gerthh better lasers, as far as intensity, spectral purity and reliability are concerned. If one can achieve tunability on the molecular side, for example by Zeeman, -Stark or Doppler-effeet, a stepwise tunable laser, such as the a molecular gas laser with its rotational manyfold may be a very good compromise.

Techniques of Laser Spectroscopy: Their Advantages and Limitationssured. A major limitation in practical applications is imposed by the attainable detection sensitivity. The answer to the question: “How few atoms, molecules or photons can still be detected at a reasonable signal-to-noise ratio?” may be of crucial importance for the successful solution of a given problem.

Synchronization of Atomic Quantum Transitions by Light Pulses observed if a perturbation pulse duration is smaller than the period of oscillations on the forbidden atomic transition. An accuracy of direct measurements of quantum transition times for trapped particles may be of the order of the ratio of two-photon transition frequency to the homogeneous width.
