Abstract. A diode laser spectrometer at 493 nm is described, which is especially suited for spectroscopy of single trapped Ba[sup +] ions. Frequency doubling of a 100 mW diode laser at 986 nm results in up to 60 mW output power at 493 nm in a bandwidth of less than 60 kHz with respect to the cavity used for locking. Reference frequencies of 18 spectral lines of Te[sub 2] near the 493 nm resonance of Ba[sup +] have been measured using modulation transfer spectroscopy. The fluorescence excitation spectrum of a single Ba[sup +] ion, measured with this laser, exhibits well-resolved dark resonances, which confirms the versatility of the system for quantum optical experiments.
