Abstract

By optimizing the intracavity dispersion compensation in a self mode-locked Ti:sapphire laser, we have generated pulses of less than 11 fs in duration. Dispersion within the laser cavity can be reduced by using a short highly-doped Ti:sapphire crystal and a prism glass which reduces third-order dispersion. Amplifier design which reduce third order dispersion have also been tested, and we have demonstrated stretching an 11 fs pulse by a factor of 1000, followed by recompression of 20 fs pulse duration. Our results demonstrate that the exceptionally broad bandwidth of Ti:sapphire can be utilized to generate pulses shorter than has been possible with any other type of laser material to date.
