Abstract

We describe how spatially resolved velocity measurements can be acquired using a pulse-amplified single-mode cw laser with a potential of single-shot measurements. The laser beam was tuned to the point of maximum slope of a Doppler-broadened absorption profile of I2, which was seeded into the flow. The beam was then split into two components and sent counterpropagating through the measurement region. By diode-array detection of the laser-induced fluorescence from I2, spatially and temporally resolved velocities can be acquired.
