Paper Abstract

A giant-pulse laser R4man probe, suitable for gas concentration detection below loo ppm with high local (o.6 mm3)and temnoral (pulse width 2o ns) resolution, is presented. Concen-tration values of some selected gaseous pollutants have been detected in pure gases and in adjusted gas mixtures ranging from the pure component (106 ppm) down to measured 65 ppm. Concentration values of loo ppm were measured with an accuracy of ±l00%. When the local resolution was not required to be so high - measurement volume about 5oo mm3 - concentration values of 65 ppr cou3d be detected with an accuracy of about ±3o%.
