    "abstract": "We demonstrate a 1 GHz prismless femtosecond Ti:sapphire ring laser which\nemits 890 mW for 7.6W of pump power over a continuum extending from 585 to 1200\nnm at -20 dB below the maximum. A broadband continuum is obtained without\ncareful mirror dispersion compensation, with the net cavity\ngroup-delay-dispersion having -50 to +100 fs2 oscillations from 700 to 900 nm.\nFurther broadening is obtained by use of a slightly convex cavity mirror that\nincreases self-phase modulation. 17% (75%) of the intracavity (output) power is\ngenerated in single-pass through the crystal, outside the cavity bandwidth and\nconcentrated in the low gain infrared region from 960 to 1200 nm. This laser\nseems well suited for optical frequency metrology, possibly allowing easier\nstabilization of the carrier-to-envelope offset frequency without use of\nphotonic fibers.",
