Measurement of Temperatures in a Shock Tube by Coherent Antistokes Raman Spectroscopy (CARS),

Abstract

To measure temperatures behind the shock wave the coherent anti-Stokes Raman spectroscopy (CARS) was applied. The optical setup consists of a frequency-doubled, Q-switched Nd-Yag laser, a narrow-band, pulsed dye laser, a colinear optical system and an optical multichannel analyser for recording the scattered CARS beam. The double-diaphragm shock tube is operated with helium and with air as driver gas and air as test gas.
