title: Microfabricated saturated absorption laser spectrometer.
abstract: We demonstrate a miniature microfabricated saturated absorption laser spectrometer. The system consists of miniature optics, a microfabricated Rb vapor cell, heaters, and a photodetector, all contained within a volume of 0.1 cm(3). Saturated absorption spectra were measured with a diode laser at 795 nm. They are comparable to signals obtained with standard table-top setups, although the rubidium vapor cell has an interior volume of only 1 mm(3). We discuss the performance and prospects for using such systems as a miniature optical wavelength reference, compatible with transportable instruments.
