Title:
WAVEFORM MEASUREMENT DEVICE AND PULSED-LIGHT-GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/163149
Kind Code:
A1
Abstract:
This waveform measurement device is provided with: an input spectrum acquisition unit for acquiring an input intensity spectrum which is the intensity spectrum of pulsed light; an optical element for inputting pulsed light, and outputting light that has an intensity spectrum corresponding to the phase spectrum of the pulsed light; an output spectrum acquisition unit for acquiring an output intensity spectrum which is the intensity spectrum of the light outputted by the optical element; and a phase spectrum determination unit for comparing an output intensity spectrum that is calculated on the assumption that pulsed light having an input intensity spectrum and a hypothetical phase spectrum has been inputted to the optical element, and the output intensity spectrum that was acquired by the output spectrum acquisition unit, and determining the phase spectrum of the pulsed light. The phase spectrum determination unit reshapes a controlled phase spectrum, and sets a hypothetical phase spectrum.
