Abstract
We have modified a commercial Ti:sapphire laser to allow optical phase stabilization to an extremely stable semiconductor laser, which in tu rn is locked to a Doppler-free resonance in a cesium vapor cell. For t ime scales from 10 mu s up to several hours the combined system has a rms linewidth of 4 kHz with respect to the cesium resonance. The syste m allows the resolution of extremely narrow resonances in a cloud of t rapped atoms.
