Abstract

The optoacoustic detection method is a well-established technique in many branches of spectroscopy. Its high sensitivity with small samples and ability to operate even at low pressure have suggested its application in high-resolution experiments; in particular, the study of Ref. 1 has shown that it can produce results of high accuracy comparable to the best alternative methods presently available. However, this technique has never been applied to the study of Doppler-free line shapes even if this approach allows investigation of situations not usually encountered in conventional measurements, such as very strong saturation in a cell placed outside the laser cavity:
