Lasers are becoming more and more commonly used to detect environmentally sensitive materials, especially if ultra-trace detection is required. Over the last few years, the laser ionisation group in Glasgow has been involved in the detection of trace

Step index, all-silica UV fibres may have an important role to play in the evolution of new spectroscopic surface techniques such as resonant laser ablation. The intrinsic and extrinsic properties of silica fibres are initially discussed in this pape

Femtosecond time-of-fight mass spectra of laser-desorbed gallium arsenide (GaAs) and trinitrobenzene (TNT) reveal the characteristic features and differences of femtosecond atomic and molecular ionization. Significant yields of multiply-charged atomi

The interaction of ultra-intense focused laser beams with solid targets is a new field of research resulting in the production of exotic plasma conditions similar to the conditions which exist in the interior of some stellar objects. The lasers gener

The dissociative ionization of CS2 has been investigated at several different wavelengths (375, 750, 395, and 790 nm), for pulse-widths as short as 50fs, and laser intensities in the range of (2.2×1013−3×1016) W/cm2. It is found from the various

The dissociative pathways of the nitromethane molecule have been studied using 10 ns, 7 ps and 90 fs laser pulses. In this paper, the differences between the dissociation channels opened using different laser pulse widths are discussed to investigate

A laser based procedure, which combines the REMPI technique and ion chamber detection to give a very high sensitivity, has been developed at Glasgow to detect urban air pollutants NOx(x=1,2) and CO. Several REMPI schemes have been tested for CO monit

An investigation into the ablated neutral plume from a super‐conducting material YBa2Cu3Oy has been carried out in terms of the laser flux and wavelength. The velocity distributions of several ablated neutral species from the target have been measu
