Demonstration of frequency comb laser spectroscopy in the vacuum-ultraviolet [PDF]

open access: yes2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
High-resolution spectroscopy at 125 nm is performed on xenon, using amplifi ed frequency comb pulse trains that are frequency upconverted in a gas cell, thereby demonstrating the potential for sub-MHz accuracy in the vacuum-ultraviolet.

Vacuum ultraviolet discharge excited lasers [PDF]

open access: yes, 1987
The thesis concerns experimental studies of discharge excited lasers operating in the vacuum ultraviolet (VUV) region of the spectrum. The known molecular fluorine laser operating at 157nm, on a bound- to-bound transition of the F2 molecule was selected for initial study.

Verdet constant dispersion of magnesium fluoride for deep-ultraviolet and vacuum-ultraviolet Faraday rotators [PDF]

open access: yes, 2023
0000-0002-7220-0613The Verdet constant dispersion in magnesium fluoride (MgF2) crystals was evaluated over a wavelength range of 190–300 nm. The Verdet constant was found to be 38.7 rad/(T·m) at a wavelength of 193 nm. These results were fitted using the

Operation of a free-electron laser from the extreme ultraviolet to the water window [PDF]

open access: yes, 2007
We report results on the performance of a free-electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent extreme-ultraviolet radiation source have been measured.

Integration of Dye Lasers and Microfluidics for Biochemical Analysis [PDF]

open access: yes, 2009
This dissertation describes the study of two important aspects of integration in microfluidics: optics and biochemistry. In optics integration, two types of miniaturized dye lasers, namely the solid-state polymer dye lasers and optofluidic dye lasers ...

New continua for absorption spectroscopy from 40 to 2000 Å [PDF]

open access: yes, 1978
The spectra of plasmas produced by focusing the output of a Q-switched ruby laser (output 1 J) on the rare-earth metals have been studied. From samarium (Z = 70), strong quasi-uniform continua are emitted in the wavelength range 40–2000 Å.

Thresholds for Laser-Induced Ion Formation from Aerosols in a Vacuum Using Ultraviolet and Vacuum-Ultraviolet Laser Wavelengths [PDF]

open access: yesAerosol Science and Technology, 1997
ABSTRACT The minimum laser fluence required for the formation of ions from aerosol particles in a vacuum as a function of a number of parameters has been investigated. Although the influences of various particle properties are complex, the threshold energy density does depend on light absorption and lattice energy.

Dual-pulse laser induced breakdown spectroscopy in the vacuum ultraviolet with ambient gas: spectroscopic analysis and optimization of limit of detection of carbon and sulfur in steel [PDF]

open access: yes, 2012
Laser Induced Breakdown Spectroscopy (LIBS) in the vacuum ultraviolet (VUV) spectral region was applied to standard steel samples in dual-pulse excitation mode with an ambient gas. Two lasers were employed in collinear geometry, one as an ablation laser (
