A high-power extended-cavity diode laser (ECDL) stabilized to the Yb resonant transition at 398.9 nm in an Yb hollow-cathode lamp was demonstrated. A frequency-dispersion signal, which was obtained by applying a modulation-free dichroic-atomic vapor laser lock technique, stabilized the violet ECDL . The violet ECDL was stabilized at a frequency stability below 1 MHz at 1-s average time and a useful output power of 15 mW.
