Description
Tunable, single-frequency laser sources are a great tool for high-selectivity spectroscopy, allowing hyperfine structure and isotope shift measurements. In this study we demonstrate monolithic diamond resonators as a narrow linewidth laser source, suitable for high-resolution spectroscopy. The Stokes field from the diamond resonator at a wavelength of 433.9 nm and linewidth of 170 MHz was used in a crossed-beams spectroscopy setup (PI-LIST). The targeted atom was 152Sm, and the ionization experiment resulted in the measurement of a 0.51 GHz FWHM spectral profile affected by saturation, which demonstrated the suitability of diamond resonators as a high-selectivity spectroscopy tool.
