flames operated at relatively high thermal loads and Reynolds-numbers in appropriate model combustors. These model combustors differ of course in various aspects from full-scale applica- tions as requirements from the measurement tech- niques enforce idealized conditions to a certain extent.
Many laser-based diagnostics developed into robust techniques applicable even under hostile environments typical for gas turbine combustors [5]. Their little intrusiveness, high temporal, and relatively high spatial resolution facilitates quanti- tative measurement of the local, transient proper- ties of the turbulent flow, and scalar field. In addition to statistical moments at single points, recent developments such as 1D Raman/Rayleigh scattering [2,6] or two-point correlation measure- ments [7] yield more precise information on scalar dissipation rates, integral length, and time scales.
