Abstract
Doppler-free two-photon rotational transitions J = 13 <--<-- 11 and J = 12 <--<-- 10 of OCS and J = 8 <--<-- 6 and J = 7 <--<-- 5 of CHF3 were detecte d in the frequency range 134-156 GHz, using a novel, highly sensitive intra cavity-jet technique. The sub-Doppler narrowing of the observed peaks (down to 40 kHz full width at half maximum as compared to 300 kHz of the Doppler width) demonstrates the potential of this new technique for high precision millimeter wave spectroscopy. The possibilities of the further reduction o f the two-photon absorption line widths are considered.
