Research team develops optical technology to simultaneously generate and shape gigahertz burst pulses

The proposed “spectrum shuttling” method generates gigahertz (GHz) burst pulses from ultrashort pulses, each with a different wavelength and customizable spatial profile. These GHz bursts open the way to a …
