Abstract
A tunable pulsed Ti:Sapphire laser was used to determine low concentra tions using intracavity absorption spectroscopy with temporal resoluti on. The dependence of the laser-pulse evolution time on the absorbance of a sample introduced in the cavity (solution of 3,3- diethylthiatri carbocyanine iodide in dimethylsulphoxide) was studied theoretically a nd experimentally. The minimal experimentally measured absorbance was 8X10(-4). The possibility was shown of using a Ti:S laser to detect ab sorbance of 10(-5) via a temporal technique.
