A solid state, wavelength-tuneable laser system is requested in order to measure the spectra and reaction kinetics of atmospheric species on environmetal surfaces. We have used fixed-wavelength laser sources with a restricted selection of atmospherically relevant compounds to make the first direct measurements of atmospherically important surface reaction kinetics and to develop probes for he local environment at the reactive interface. The acquisition of a tuneable laser system will allow us to measure the heterogeneous atmospheric reaction and partitioning behaviour of many more atmospherically important compounds.

为了测量金属表面大气组分的光谱和反应动力学，需要一种波长可调谐的固体激光系统。我们已经使用固定波长的激光源与大气相关的化合物的有限选择，使大气重要的表面反应动力学的第一次直接测量，并开发探针，他在反应界面的局部环境。获得可调谐激光系统将使我们能够测量许多在大气中更重要的化合物的非均相大气反应和分配行为。
