  • Patent number: 12250473
    Abstract: A method and a system for imaging a dynamic scene, by time-spectrum mapping when a single chirped pulse probes the dynamic scene, storing temporal information at different wavelengths, spectral shearing, spatial encoding and reverse spectral shearing; spatiotemporal integration; and image reconstruction from a resulting captured snapshot, using a laser source configured to emit a linearly chirped laser probe pulse; an imaging unit; a shearing and reversing shearing unit; an encoder; a detector; and a computer; wherein the imaging unit is configured to record the linearly chirped laser probe pulse transmitted by the dynamic scene in a snapshot; the shearing and reversing shearing unit is configured to spectrally shears the linearly chirped laser pulses received from the imaging unit to the encoder, the detector records a compressed snapshot of a temporal information of the dynamic scene read out by the probe pulse; and the computer processes the snapshot and yields a(x,y,t) datacube of the dynamic scene.

  • Patent number: 9910339
    Abstract: A method and a system for nonlinear optical interaction in a nonlinear medium, comprising interacting at least one input beam in a nonlinear medium located at a spectrally dispersed plane. The method and system allows generating output photons from input photons, the output photons having properties that linearly depend on the properties of the input photons and that are mutually independent, comprising interacting the input photons in a nonlinear medium located at a spectrally dispersed plane.

  • Patent number: 9203208
    Abstract: A system and method for high power parametric amplification based on performing amplification in a frequency domain after time domain pulses are optically Fourier transformed, to overcome bandwidth limitations. In a nutshell, a first optical Fourier transformation of a seed spectrum is performed and parametric amplification is carried out in this spatially dispersed frequency plane. As a consequence, individual parts of the spectrum can be amplified using an optical amplification medium comprising a series of optical amplification units, such as different narrowband crystals, placed one next to each other. Each crystal is tuned independently to optimize its corresponding spectral slice. A second optical Fourier transformation recovers the time domain laser pulses. This method enables scalability of amplified bandwidth and pulse energy at the same time.
