Abstract

We demonstrate a 1GHz prismless femtosecond Ti:sapphire ring laser that emits 890mW for 7.6W of pump power over a continuum extending from 585to1200nm at 20dB below the maximum. A broadband continuum is obtained with the net cavity group delay dispersion having 50to100fs2 oscillations from 700to900nm. Further broadening is obtained by use of a slightly convex cavity mirror that increases self-phase modulation. Approximately 17% (75%) of the intracavity (output) power is generated in single pass through the crystal, outside the cavity bandwidth, and concentrated in the low-gain IR from 960to1200nm.
