  • Methods and apparatus for measuring and locking ultra-fast laser pulses
    Patent number: 11522334
    Abstract: Methods and devices are described for performing an all-phase measurement of an ultra-fast laser pulse having a spectral range of greater than one octave. The ultra-fast laser pulse may be split into a first beam comprising a fundamental light with a wavelength ?0 and a second beam comprising a light with a wavelength 2?0. The light with the wavelength 2?0 may be frequency doubled to a light with a wavelength ?0 to generate an interference with the fundamental light. Fourier transform may be performed on an interference spectrum of the interference, and a relative envelope delay (RED) between the fundamental light and the frequency doubled light and a carrier envelope phase (CEP) may be acquired based on a result of the Fourier transform.

  • SUPERCONTINUUM COHERENT LIGHT SOURCE
    Publication number: 20190346737
    Abstract: The present invention provides a supercontinuum coherent light source, comprising: a laser generation device configured to generate a laser pulse having a peak optical intensity at a beam waist of the laser pulse being 0.47-0.94×1013 W/cm2; and, a set of solid thin plates configured to spectrally broaden the laser pulse to generate a supercontinuous spectrum. The supercontinuum coherent light source of the present invention has an efficiency of up to 87% and the spectrum is broadened to more than one octave.
