Abstract
The technique of broad-band laser intra-cavity absorption spectroscopy was amended by the injection of light pulses into the absorber, for recording of Na 3S–5S two-photon absorption spectra. The contributions of the P fine structure levels to the two-photon amplitude interfere constructively or destructively depending on tuning and polarisation of the pulsed light: The transition probability vanishes completely at a particular tuning between the D lines only for parallel polarisation of the lasers.
