Abstract

The third-order dispersion of a modelocked Ti:Al₂O₃ laser can be reduced by using quartz prisms for dispersion control. Two such lasers have been constructed, one which uses a novel sequence of four quartz prisms and a second which uses a pair of quartz prisms. The laser which incorporates four quartz prisms allows transform-limited 13-fs pulses to be generated with a gain crystal 20 mm long. The second laser has four times less third-order dispersion but does not produce pulses shorter than 15 fs. Evidence is presented to show that third-order dispersion is not limiting pulse duration.
