A novel scheme of collinear fast beam laser spectroscopy for the detection of the long lived rare isotope {sup 85}Kr by observing the optical hyperfine structure spectrum is presented. The technique utilizes cascade two-step excitation to pump metastable krypton atoms to a high-lying Rydberg level. The present work on krypton was motivated by the fact that {sup 85}Kr is a major tracer gas for exploring the reservoir structure of large oil fields. {sup 85}Kr detection in ambient air is also of importance for monitoring nuclear activities on a world wide scale. The technique has been successfully applied to stable krypton isotopes and to {sup 85}Kr. The selectivity is at the one part in 10{sup 10} level and the sensitivity at a few hundred ions/s.
