Vacuum-ultraviolet anti-Stokes Raman laser with atomic selenium

Optics Letters, 1985
The achievement of anti-Stokes Raman-laser oscillation in atomic Se at 158.7 and 167.5 nm using pump-laser radiation at 199.5 and 254.8 nm is reported. The necessary population inversion between the (1)S(0) and lower (1)D(2) or (3)P states is achieved by photodissociation of COSe molecules with ArF-laser radiation.

Photosensitivity in glasses: comparing ultrafast lasers with vacuum-ultraviolet lasers

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Technical Digest (IEEE Cat. No.01CH37170), 2001
Summary form only given. Laser microfabrication technology is a promising photonics processing approach with parallels to the current use of lasers in semiconductor lithography, trimming, repair, and inspection. To this end, our groups are exploring two extreme forefronts of laser technology - ultrafast (UF) and deep-ultraviolet (UV) lasers - to drive ...

Vacuum ultraviolet laser emission from C IV

Applied Physics Letters, 1973
Laser emission from C IV resonance lines at 1548.2 and 1550.8 Å has been produced in a mirrorless traveling-wave transverse-discharge system. The gain of the 1-m-long device has been measured to be 8.7 dB/m, and the peak power is estimated to be a few kilowatts.

Vacuum Ultraviolet Laser Spectroscopy of Molecular Autoionizing States

Short Wavelength Coherent Radiation: Generation and Applications, 1988
This paper describes a new apparatus which uses coherent vacuum ultraviolet light to photoionize molecules in a supersonic molecular beam, and energy analyzes the resulting photoelectrons by time of flight spectroscopy. The broadly tunable coherent VUV is generated by four wave sum mixing in Hg.

Laser radiometry for the vacuum-ultraviolet spectral range

CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005., 2006
In 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 emission from Nd+3:LaF3

Applied Physics Letters, 1985
Laser emission at 172 nm has been produced by pumping a Nd:LaF3 crystal with incoherent Kr*2 radiation at 146 nm. The 5-ns pulse contained approximately 20–30 μJ of energy. Fluorescence measurements indicate potential for tuning from 170–175 nm, which should be observable with OH−-free crystals.

Vacuum Ultraviolet Laser Spectroscopy of Small Molecules

1988
Publisher Summary This chapter presents a short coverage of various methods which have recently emerged with the advent of tunable coherent vacuum ultraviolet sources. Using lasers with sufficiently small pulse duration, time-of-flight spectrometers can also be particularly advantageous.

High-Brightness Deep and Vacuum Ultraviolet Laser Sources

Laser Congress 2024 (ASSL, LAC, LS&C)
Bright light sources in the far-ultraviolet (100-300 nm), based on resonant dispersive-wave emission in hollow-capillary fibres, open many important scientific and industrial opportunities. In this talk we review this technology and describe our recent progress.

Vacuum ultraviolet laser spectroscopy of jet cooled halogens

Annual Meeting Optical Society of America, 1989
VUV spectra involving ion-pair states for many of the halogens have been known since the beginning of quantum mechanics. To date, the use of synchrotron radiation has offered the most flexible method to record these spectra. However, since vertical transitions from the ground state probe very high ion-pair state vibrational levels, room temperature ...
