A real-time spatiotemporal processing techniques by time-to-space conversion using three-wave mixing in a second-order nonlinear crystal and space-to-time conversion by a four-wave mixing arrangement is described. The method employs cascaded second-order nonlinearities for enhanced conversion efficiency. An ultrafast waveform imager performs serial-to-parallel demultiplexing of the shaped pulse train into parallel spatial channels for electronic detection, while an ultrafast synthesizer performs parallel-to-serial multiplexing of a parallel spatial image into a serial pulse train with femtosecond response time and high conversion efficiency.
