Sub-Doppler lines of Cs{sub 2} were investigated with a Nd:YAG laser. Modulation transfer spectroscopy and FM spectroscopy were applied to yield error signals that were used for absolute stabilization of the laser frequency. The frequency stability was characterized with an I{sub 2}-locked dual-wavelength Nd:YAG frequency reference. The root Allan variance of the beat frequency reached a minimum of 1.3{times}10{sup {minus}11} (beat frequency fluctuations of 3.65 kHz) for a measurement time of 20 s. Absolute frequencies of several Cs{sub 2} lines were determined with an accuracy of {approximately}1 MHz. Further improvement in sensitivity was demonstrated by insertion of the absorption cell into a Fabry{endash}Perot cavity. While the laser was locked to the cavity, the cavity length was modulated and the transmitted probe beam was detected at the third harmonic of the modulation frequency. {copyright} {ital 1996 Optical Society of America.}
