A number of previous conferences on tunable diode laser absorption spectroscopy (TDLAS) have been held over the past several years in the United States, Europe, and Russia. This conference brought together scientists and engineers involved in fundamental and applied research, as well as commercial applications of tunable diode lasers, and other IR sources for studying the atmosphere and industrial process monitoring. In the first session, various papers were presented describing new semiconductor devices for achieving outputs in the visible to near-IR spectral region. Along with discussions of device characteristics, several new applications of these devices were presented. The second session focused on several new advances in the field, including identification of factors which limit the performance of instruments employing multipass cells, the application of spectral correlation techniques, and the use of TDLAS with cold molecular beams and low-temperature cells. Two new laboratory kinetic studies employing TDLAS were also presented. The third session focused on recent field applications of this technique. Presentations in this area included recent ground-based, shipboard, and aircraft measurements of various important trace gases in atmospheric studies. These studies were carried out by research groups in Germany, the United States, Canada, and Japan. In addition, improvements in TDLAS methodology were presented along with a critical assessment of criteria employed in evaluating instrument performance. The conference concluded with a fourth session which featured a number of new systems for process control and combustion monitoring. Papers within the scope of the data base have been processed separately.
