  • Publication number: 20240102866
    Abstract: A system for characterizing a pulse of electromagnetic radiation by time-resolved optical gating, which includes an interference-forming device which is adapted for superimposing four parts of the pulse. The system also includes a matrix image sensor which selectively captures, based on two-photon absorptions, an interference pattern formed by the pulse. The system allows obtaining the pulse shape completely and accurately, and is particularly suitable for characterizing ultrashort pulses. Also, the two-photon absorption can be produced in the matrix image sensor, or replaced by optical frequency doubling which is produced by an SHG crystal plate.
