Abstract
A method of velocimetry of gaseous flows based on resonant degenerate four-wave mixing (DFWM) is described. Spatially resolved velocity meas urements are derived from Doppler shifts of DFWM signals generated in NO-seeded into flows of air or Nz. Velocities in the range of 60 to 20 0 ms(-1) have been measured with an uncertainty of +/-30 ms(-1).
