We produced ultraviolet radiation by frequency tripling the mode-locked emission of an external cavity laser containing a tapered GaAlAs amplifier gain element. The 429-nm second harmonic produced by a KNbO{sub 3} crystal was sum-frequency mixed with the 858-nm fundamental in a Li{sub 3}BO{sub 5} crystal, generating as much as 50{mu}W of power at 286 nm. {copyright} {ital 1995} {ital Optical} {ital Society} {ital of} {ital America}.
