UltraFast Innovations (UFI) Third Order Dispersion (TOD) Ultrafast Mirrors provide high throughput, zero group delay dispersion (GDD) and highly negative third order dispersion. These TOD mirrors compensate for the dispersion typically introduced by grating compressors for pulse durations below 50 femtoseconds. At an angle of incidence of 7°, these mirrors feature high reflectance >99.9% for p-polarization to limit losses in laser compressors. UltraFast Innovations (UFI) Third Order Dispersion Ultrafast Mirrors are ideal to compensate for TOD without introducing additional GDD. Please contact us if your laser system requires a custom size, wavelength, or pulse profile.
