Vacuum ultraviolet laser radiation

For ion TOF measurement a probe laser was used to ionize reaction products in the reaction zone. The (1 + F) resonance-enhanced multiphoton ionization (REMPI) method was adapted for H-atom detection. The necessary vacuum ultraviolet (VUV) radiation near 121.6 nm (for Lyman-a transition) can readily be generated by a frequency-tripling technique in a Kr cell.37 The sensitivity of this (1 +1 ) REMPI detection scheme is extremely high owing to the large absorption cross-section of Lyman-a transition,...

Theoretical developments [250], the requirements for vacuum ultraviolet phosphors, the search for blue and ultraviolet solid-state lasers, coupled with improvements in the construction of vacuum ultraviolet spectrometers [251] and the easier access to synchrotron radiation, have led to a recent upsurge of interest in 4fN-4fN15d1 spectra of rare earths. Just as in the case of 4fN 4fN Spectra [207], the 4fN-4fN 15d spectra of lanthanide ions in octahedral symmetry environments comprise much more detailed structure than in the case of low symmetry systems.

ABSTRACT. Tunable coherent radiation in the ultraviolet and vacuum ultraviolet has been generated by stimulated Raman scattering, by anti-Stokes Raman lasers, and by frequency mixing processes in nonlinear media. The theory and experimental progress in the development of these laser-driven sources is reviewed, and examples of available systems and their characteristics are discussed. Various applications in spectroscopy of radiation tunable in the wavelength region 200-90 nm are presented.

Practically all laser analytical techniques are based on systems with tunable wavelength. By using different types of lasers and the methods of nonlinear optics, one can obtain intense tunable laser radiation over the spectral range of 0.2-40 pm and in some regions of the vacuum ultraviolet and far infrared. Almost any strong...
