Abstract

Doppler-free intracavity two-photon absorption in gas phase naphthalene was demonstrated for the first time. A cw tunable dye laser system was modified to incorporate an intracavity absorption gas cell for this work. A detailed description of the experimental apparatus is given. This technique has many advantages over the conventional pulsed-type set-up, and is applicable to other atomic and molecular systems. The observed linewidths of Doppler-free two-photon rovibronic features of naphthalene S1 ← S0 excitation spectrum are on the order of 300 MHz. The combined effects of the laser width, frequency scanning rates and the high density of states prevented us from resolving individual robrivonic lines.
