Paper Abstract

This paper describes the features of the copper vapor laser developed in IHI Research Center for measurement of high-speed fluid, and the preliminary results of observed measurement on actual fluid flow in a shock tube. The copper vapor laser we have developed selects two different wavelengths (green or yellow) and couples them with an optical fiber. Further, in correspondence with external triggering from a shock tube or other devices, it is possible to freely set the timing for generation of laser pulses. Applying the copper vapor laser for the schlieren light source, we were able to visualize the formation of shock waveforms around an airfoil placed in a shock tube.
