Abstract
The bandwidth of titanium-doped sapphire is sufficient to generate pulses ≪10 fs in duration; however, the current generation of mode-locked Ti:sapphire lasers is limited to pulses of ~50 fs. We demonstrate that this limitation is primarily due to third-order errors in group-velocity dispersion caused by the intracavity prism pair. By optimizing this dispersion, to date we have generated near transform- limited pulses of 32-fs duration—we believe this is a new record for a solid- state laser.
