Abstract

A frequency-doubled Nd:YAG/glass laser system has been assembled for use at the newly constructed Combustion Research Facility at Sandia National Laboratories, Livermore. The doubled radiation (532 nm) will be used to make single-shot Raman spectroscopy studies of ongoing combustion processes. Occurrences of breakdown of the combustion gases should be reduced because of the long 2- μsec pulse. The small beam divergence of the green radiation should easily allow 1-mm spatial resolution in the combustion chamber.
