Active manipulation of light beams is required for a range of emerging optical technologies, including sensing, optical computing, virtual/augmented reality, dynamic holography, and computational imaging.
Stanford researchers at SLAC have designed a multi-frequency klystron that achieves efficiencies higher than conventional single frequency klystrons and simultaneously delivers substantial power at higher harmonic(s).
To determine the phase and magnitude of the complex electric field of
weak ultra-short pulses we propose to use a dummy strong pulse time
delayed relative to the weak pulse that needs to be characterized. This
