Abstract :
We obtained an ultraviolet frequency comb of 1.58 W in average power by frequency quadrupling a high-power large-mode-area fiber chirped-pulse amplifier at 1032 nm, whose carrier envelope phase was stabilized down to a linewidth of 2.42 m Hz via feedback control on the Ti:S seed oscillator.
