Laser-Based Optical System for Reactive Radical Concentration Measurements in Plasmas and Flames

Abstract

Defense University Research Instrumentation Program (DURIP) funding was used to assemble a multi-purpose optical diagnostic system for in-situ radical concentration measurements in plasma and combustion systems. The system was configured to allow two-dimensional measurements (using a single wavelength) of important radical concentrations in stationary or time-averaged plasma and flame conditions, to make simultaneous nanosecond-resolved single point measurements at this wavelength, and to collect one-dimensional information about the spectral lines in rotational bands for the species of interest. The' system consisted of a Nd:YAG pumped optical parametric oscillator (OPO), a Raman spectrometer, two intensified CCD cameras, and associated optics.
