报告摘要：

Laser diagnostic techniques have for more than five decades been used for gaining a deepened understanding of various combustion processes. The main reason for this is the possibility of non-intrusive measurements of key combustion parameters, e.g. species concentrations, temperatures and velocities, with high spatial and temporal resolution.

The presentation will describe some development of the techniques themselves, followed by applications of relevant diagnostic techniques for studies of combustion phenomena and then more applied activities often related to challenges in an industrial environment.

After a short introduction and background some common laser diagnostic techniques will be briefly described. Then some emerging techniques will be described, e.g. enabling high speed visualization/3D imaging, single ended diagnostics as well as backward lasing. In the category of studies of combustion phenomena, the presentation will focus on diagnostic challenges and applications when studying combustion of some renewable fuels; solid biomass, ammonia and metals. In the field of applied diagnostics, preferably in an industrial environment, examples will be given from IC engines, gas turbines as well as full-scale industrial furnaces.

The presentation will be concluded with a summary and some thoughts about the future.
