Laser and probe diagnostics in fundamental combustion research

Combustion diagnostics using lasers has matured considerably during the las t decade. By now, lasers are routinely relied upon in many practical applic ations where direct inspection of the combustion process is necessary. Quan titative information, however, may still be a major challenge. In this arti cle, some essential features of laser techniques for fundamental combustion research are discussed in view of their potential and limitations. Laser m ethods are complemented by molecular beam mass spectrometry. Applications i nclude diagnostics in laminar and turbulent diffusion flames, in fuel-rich and sooting flames, and in combustion chemical vapor deposition (CVD) of th in diamond films. Avenues for further research will be discussed.
