Asynchronous Optical Sampling for Laser-Based Combustion Diagnostics in High-Pressure Flames

Abstract

This report describe the progress on the development of a new laser based combustion diagnostic for the quantitative measurement of both major and minor species in high pressure flames. The technique, Asynchronous Optical Sampling (ASOPS), is a state of the art improvement in picosecond pump/probe spectroscopy. Final results from the study of atomic sodium in an atmospheric flame are presented. The first ever UV pump/UV probe ASOPS signal for atomic indium is shown. Techniques for noise reduction are discussed along with initial results. (jhd)
