Abstract
An ultrafast laser for delivering ultra-short duration seed-pulses for further amplification has a resonator including negative group delay dispersion (NGDD) mirrors for minimizing increases in the duration of the pulses due to positive group delay dispersion effects inherent in the resonator. The NGDD mirrors could be configured such that the pulses had a Gaussian spectrum. Instead, however, the NGDD mirrors are configured and arranged such the pulses have a non-Gaussian spectrum. The non-Gaussian spectrum has a FWHM bandwidth significantly greater than that of the Gaussian spectrum.
