The pulsed writing of volume holograms in lithium niobate is reported, both with 200-nsec and 20-nsec duration pulses. This information is of particular interest in high capacity information storage applications since it indicates that writing times

Laser‐induced fluorescence has been used to measure the velocity, direction, and divergence of a beam of neutral hydrogen atoms traveling at 50 MeV or one‐third the speed of light. The beam was produced by neutralizing a negative hydrogen ion bea

The use of laser spectroscopy for the determination of momentum spread and energy of a relativistic H− beam is discussed, and the results are presented of a successful attempt to reduce the momentum spread δpp by a factor of 5 from its initial val

The results are presented of further studies of the effects of electric fields on the photodetachment cross section of ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$, for both \ensuremath{\pi} and \ensuremath{\sigma} polarization. Data are fitted to the th

A new method for H − beam-energy and energy-spread diagnostics is proposed. This method is based on the interaction of a short-wavelength (150–300 nm) laser colliding at 0° with a relativistic H − beam. The interaction results in the capabilit

Using crossed laser-relativistic ion beam (800 MeV) techniques, we have measured two- and three-photon detachments of the 0.75 eV bound electron in H_ as a function of CO2 laser photon energy, intensity, and polarization. The threshold region for pho

Over the last two decades, Mexico City, like many large industrial and populous urban areas, has developed a serious air pollution problem, especially during the winter months. In February of 1991, a major measurements campaign was carried out in an

Optical Remote Sensing of the Atmosphere.
A lidar system based on ultraviolet (UV) laser induced fluorescence (LIF) has been developed for the remote detection of atmospherically dispersed biological particles, such as the vegetative cells of bacillus thuringiensis (BT) and bacillus globiggi
