Phase and Angular Momentum Spectroscopy with Frequency Comb Lasers
Abstract
Objective of this proposed work is to create new phase and orbital angular momentum diagnostics aimed at accessing species, temperature, and flow structure information using the exquisite coherence properties of frequency comb lasers. The diagnostics will share the simple setup and portability characteristics of their predecessor absorption systems. They will address two major challenges to current combustion diagnostics: (1) measurement of temperature and multiple species concentrations at pressures above 100 atm, (2) turbulent flow structure characterization using single-beam diagnostics requiring limited optical access. The techniques we develop will be demonstrated in laboratory environments and where possible, validated against imaging and computational results.
