Vacuum ultraviolet laser spectra of ICl
The Journal of Chemical Physics, 1989Vacuum ultraviolet fluorescence excitation spectra of jet cooled ICl have been recorded between 158 and 166 nm using a VUV ‘‘laser’’ generated by four-wave sum-mixing in Mg vapor. An unambiguous vibrational analysis of the spectra has shown that transitions from v″=0 of the ground state probe high vibrational levels of the first tier EO+ ion-pair state

Xenon molecular laser in the vacuum ultraviolet
IEEE Journal of Quantum Electronics, 1973Vacuum ultraviolet emission from high-pressure Xe gas under excitation by a pulsed electron beam has been investigated. When cavity mirrors were provided, significant line narrowing and a thousandfold increase in spectral intensity occurred at 1730 ± 10 A.

Microanalysis by Laser-Induced Plasma Spectroscopy in the Vacuum Ultraviolet
Analytical Chemistry, 2004A new setup for microanalysis by laser-induced plasma spectroscopy in the VUV range is presented and described in detail. The system features an integrated ablation and detection module with a newly designed VUV echelle system. The echelle permits a full spectral coverage between 150 and 300 nm with a resolving power lambda/Deltalambda between 11,000 ...

Tunable vacuum ultraviolet laser action by argon excimers
Applied Physics Letters, 1980Vacuum ultraviolet lasing was achieved in electron-beam-pumped high-density argon gas (25–65 bars). With a diffraction grating, the argon excimer laser (126 nm) could be tuned between 123.2 and 127.4 nm. The line width of the tuned laser was 0.6 nm and the output power ∼1 kW.

Generation of vacuum ultraviolet radiation for precision laser spectroscopy
Applied Optics, 1997We report on the generation of tunable nanosecond pulsed VUV radiation near 120 nm using difference-frequency mixing in H(2). Our scheme uses two dye lasers, one fixed at 606 nm and the other tunable in the red. These convenient wavelengths simplify the metrology needed for accurate VUV laser spectroscopy.

Publisher Summary The chapter discusses vacuum ultraviolet lasers. Laser plasma ultraviolet (XUV) lasers (XRL) and high-order harmonic generation (HHG) are new sources. For both sources, the short-wavelength limit of the physical process is about a few nanometers, but the intensity and other beam qualities required for most practical uses are ...

Laser radiometry for the vacuum-ultraviolet spectral range
CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005., 2006In this presentation, we report on the characterization of a new standard detector for the F/sub 2/ laser radiation at 157 nm and on the results of the first calibrations at 157 nm in nitrogen atmosphere at average power levels close to 1 W. For production control, standardization and safety regulations during testing and production, calibrated ...

Vacuum Ultraviolet Laser Ablation of Teflon (PTFE)
MRS Proceedings, 1992ABSTRACTVacuum-ultraviolet laser ablation of Teflon is reviewed. The 157 nm irradiation of Teflon produces clean ablation sites well suited to micromachining applications in the electronics and medical fields. At 193 nm, etching profiles are poorly defined, showing swelling characteristics commonly produced by longer wavelength lasers.
