Paper Abstract

A technique is discussed which allows the performance of extremely sensitive and isotope selective trace analysis. It applies resonant Dopppler-free two-photon laser spectroscopy and thermionic detection of the selectively excited and collisionally ionized species. If lasers are used whose optical frequencies can be tuned very fast from one isotopic resonance to the others, even in very small samples, isotope ratios can be determined by spectroscopic means with good precision ('optical mass spectrometer'). Before all other laser systems, semiconductor lasers meet the requirements of fast frequency tunability.
