Paper Abstract

Two laser-based techniques, Optoacoustic Laserbeam Deflection (OLD) and Frequency Modu-lation (FM) spectroscopy, were introduced for flame diagnostics. Flame temperature was measured by OLD with 1.5% precision and flame temperature profiles were taken. Ground state and excited state sodium within an aspirated flame were detected by FM-spectroscopy. Present limits of sensitivity are absorptions of 1.5 . 10-4 and ground state sodium densi-ties of 3.3 • 106 cm -3.
