      Vacuum ultraviolet (VUV) radiation may be employed to perform single-photoionization (SPI) mass spectrometry (MS). Advantages of the use of VUV include its application to all compounds with ionization potentials below eV, its inability to ionize background gases, and minimal ion fragmentation compared to most other ionization methods. This book will be very valuable to physicist and graduate students inclined to this field of interest. Show less. Some Aspects of Vacuum Ultraviolet Radiation Physics presents some data on the state of research in vacuum ultraviolet radiation in association with areas of physics. Organized into four parts, this book begins by elucidating the.

After spectral resolution in a monochromator the vacuum ultraviolet radiation is detected with an electron multiplier tube.

    Vacuum ultraviolet ellipsometric optical measurements were made on DC silicone to determine the depth of absorption of vacuum ultraviolet light as a function of wavelength. These data indicate the depth within which VUV radiation can cause material degradation. Other articles where Vacuum-ultraviolet radiation is discussed: spectroscopy: Broadband-light sources: intense sources of ultraviolet and vacuum-ultraviolet radiation, and so excitation in an electron discharge remains a common method for this portion of the spectrum. (The term vacuum ultraviolet refers to the short-wavelength portion of the electromagnetic spectrum .

STOICHEFF Department of Physics, Uniuersity of Toronto, Toronto, Ontario, M5S 1 A7, Canada IResearch supported by the Natural Sciences and Cited by: Tunable coherent radiation is generated in the vacuum ultraviolet down to nm using random quasi-phase matching in strontium tetraborate, the shortest wavelength ever produced with a second-order nonlinear optical process in a solid-state material.

Relevant properties of this radiation, the nonlinear process, and the nonlinear crystal are by:   Generation of continuously tunable coherent vacuum-ultraviolet radiation in Cd vapor.

The paper describes the use of nonlinear optical techniques for the generation of coherent radiation at ultraviolet, vacuum ultraviolet, and soft x-ray wavelengths.

Mixtures of metal vapors and inert gases, and other mixed gas systems, allow generation to regions of the spectrum where nonlinear optical crystals are opaque; and also allow. It is shown that resonantly enhanced, four-wave frequency mixing in Zn vapor provides coherent vacuum-ultraviolet radiation that is continuously tunable over.

Coherent radiation at several wavelengths in the vacuum ultraviolet (VUV) has been generated by four-wave parametric oscillation in mercury vapor. When a powerful ultraviolet pump laser of frequency ωp is tuned to a two-photon resonance, VUV signal photons at frequency ωs, as well as idler photons at frequency ωi, are generated such that ωs + ωi = 2ωp.

A frequency-doubled. Generation of tunable vacuum ultraviolet radiation down to nm has been achieved by means of type-I sum-frequency mixing with the outputs of the fifth harmonic of a Nd:YAG laser and on optical parametric oscillator (OPO) pumped by the second harmonic of the same Nd:YAG laser in a LiB 3 O 5 crystal.

Tunable coherent radiation is generated in the vacuum ultraviolet down to nm using random quasi-phase matching in strontium tetraborate, the shortest wavelength ever produced with a second. Coherent extreme-ultraviolet (EUV) radiation produced by means of high-order harmonics generation (HHG) from intense laser pulses is used for various ultrafast pump–probe experiments.

In this study, we test bulk sapphire as to its HHG capability as a new solid EUV emitter operating with moderate nJ-energy laser pulses obtained directly from an oscillator.

The direct aproach to generation of coherent radiation in the vacuum ultraviolet (VUV) is, of course, through the development of suitable lasers. There has been considerable progress in this area of laser research, as shown in Table I. Molecular hydrogen provided the first medium for laser emission in the Å region in [1], and later.

We report the observation of coherent uv emission at ± nm when sodium vapor in a heatpipe is irradiated with a pulsed visible dye laser with output wavelength in the – nm region.

It is found that intense uv emission can be produced from Na atoms as well as from Na2 molecules. The excitation functions and their dependence on vapor density and laser power.
