The technique—chirped wavelength encoding and electronic time-domain sampling (CWEETS)—transforms the temporal envelope of a signal into its spectrum using group-velocity dispersion (GVD ...

Ti:S ultrafast laser polarizers with high extinction ratio, broad spectral bandwidth, high laser damage resistance and minimal group velocity dispersion (GVD). Alpine Research Optics (ARO, Boulder, CO ...

The new laser’s Group Velocity Dispersion (GVD) precompensator provides seamless, hands-free adjustment of negative dispersion from zero up to a maximum of 43,000 fs² – enabling unmatched pulse ...
