Abstract

We have designed and demonstrated two wide-bandwidth frequency doublers capable of second-harmonic generation over the entire 100-nm cavity optics bandwidth of a passively mode-locked Ti:Al₂O₃ laser with no loss in conversion efficiency across the bandwidth. The frequency doublers are passive, utilizing prism dispersion to achieve phase matching over this bandwidth, and exhibit minimal pulse broadening that is due to group-velocity dispersion. Our calculations show that the theoretical bandwidth of these dispersive frequency doublers extends across nearly the entire Ti:Al₂O₃ laser tuning range.
