| Popis: | We have demonstrated the extremely small detection limits that can be achieved in a high‐pressure environment by the combination of saturated absorption and nonresonance emission spectroscopy. The method of SONRES exploits efficient energy transfer between excited atomic states at high pressures and intense optical fields available from tunable lasers. An estimated 104 atoms/cm3 of sodium were monitored in a flame; the corresponding atomic concentration was 1 part in 1015. A detection limit of ∼10 atoms/cm3 was recorded for sodium in argon. The ultimate detection limit for this method is ∼10−4 atoms. |
