Development of a cavity enhanced Thomson and Raman scattering diagnostic Conference Paper uri icon


  • © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All right reserved. We report on the advancement of the Cavity Enhanced Thomson Scattering (CETS) diagnostic relative to previous work. Incorporation of a secondary means to provide fast feedback for cavity locking has resulted in significant improvements over the previous system. The improved lock has resulted in an intra-cavity power of 7 W generated from an incident power of 5 mW, which corresponds to a power build-up factor of 1400. We present data on the measurement of Rayleigh scattering in laboratory air and rotational Raman scattering in nitrogen.
