Abstract
Research on emission spectroscopy and term analysis is being pursued with emphasis on the analysis of the spectra of multiply ionized inert gases. In the basic atomic laser spectroscopy group the experimental activities employing CW high-resolution techniques and time-resolved methods are well integrated with a theoretical atomic physics programme. A precision method for lifetime measurements using a mode-locked dye laser in conjunction with photon counting techniques has been further refined. Pulsed level-crossing, optical-double-resonance and quantum-beat spectroscopy have been used extensively to attain new accurate data. Studies of terawatt laser generation techniques have been made in preparation for the establishment of such techniques at the Lund Laser Center. For several years, a major project concerned with combustion diagnostics using lasers has been pursued in Lund. Many aspects of flame kinetics, NO{sub x} and soot formation, turbulence and spark ignition are being studied using laser-induced fluorescence. Raman and CARS spectroscopy. Theoretical work on kinetics and spark ignition supplements the extensive programme. Methods for combustion diagnostics based on multicolour imaging, degenerate four-wave mixing and diode-laser frequencymodulation spectroscopy are being developed. Environmental remote sensing using optical techniques is another applied spectroscopy project. Our mobile lidar system has been extensively used for range-resolved mapping of

During the last two years our activities in the medical field have increased. A research programme on cancer tumour detection and treatment using lasers is being pursued jointly with the Lund University Hospital. Work on spectroscopic diagnostics of atherosclerotic plaque is also being actively pursued, aiming at spectroscopic guidance in fibreoptic plaque ablation using excimer laser radiation. Measurements have been performed during open-heart surgery.}
