✦ Synopsis

An automated CARS N2-tbermometry capable of single-shot instantaneous mmperana~ measurements with a laser repetition rate of up to 20 Hz is described. A novel means of extracting a CARS signal in the three mixed-beam configuration by multiple reflections between two dichroics is proposed. An example of the measurement data is presented for a turbulent diffusion flame. The data of 100 events by the shot rate of 20 Hz exhibited a near-Gaussian distribution with an rms value of 93 ° at a mean temperature of 1782K.
