Narrowband Tunable VUV/XUV Radiation Generated by Third-Order Frequency Mixing of Laser Radiation iniolet (VUV) at wavelengths λ.=100–200 nm and of the extreme ultraviolet (XUV) at λ.=58–100 nm. The pioneering work in this field has been published more than ten years ago by Ward and New., Harris and Miles., Miles and Harris. and Kung et al.. During the past decade the results of a large number of

Laser and Synchrotron-Based Excitation Sources for Relaxation Studiesd 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 br

Diode Lasers and their Application to Spectroscopydiode lasers has advanced considerably in the past few years as has their availability. Because these lasers are practical, efficient and inexpensive they will open many research possibilities. Their low cost is particularly significant for laboratories with limited budgets. The impact of diode lase

The Co-Overtone Laser a Spectroscopic Source in a Most Interesting Wavelength Regionh 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 compr

High Resolution Far Infrared Spectroscopyopy. The pure rotational transitions of light molecules, for example diatomic hydrides, occur in this region; FIR measurements provide the only accurate means of determining their rotational structure and associated characteristics such as line strengths, pressure broadening parameters, and permanen

High Resolution Spectroscopy of Atomic Hydrogen: Measurement of the Rydberg Constante one at the present time . We briefly survey here the methods which have been chosen by various groups to measure this constant during the few past years, and we detail the experimental arrangement which has allowed us to obtain our result.
