We report on the development and characterization of continuous, narrow-band, and tunable laser systems that use direct second-harmonic generation from blue and green diode lasers with an output power level of up to 11.1 mW in the mid-ultraviolet. One of our laser systems was tuned to the mercury 61S0 → 63P1 intercombination line at 253.7 nm. We were able to perform Doppler-free saturation spectroscopy on this line and to lock our laser to the transition frequency on long time scales.
