Measurement of space and time profile of shaped ultrafast optical pulses using spatial-spectral interference

Summary form only given. In many fields, including optical information processing and coherent control of matter arbitrary shaping of femtosecond optical pulses is expected to bring a large number of benefits. Therefore, great expectations are held to the capability of a frequency domain pulse synthesizer, which is achievable by modulating the amplitude and the phase of an ultrashort pulse at a Fourier frequency plane without any fast response devices. In this work, we successfully verified the space and time coupling of the profile of a shaped pulse directly from a pulse shaper. The experimental setup is shown. The effect of space and time coupling appears on the identical axis as the spatially dispersion direction of the grating. For the purpose of detaching the space information from the time information, the beam profile is rotated by 90 degrees with a pair of mirrors before the pulse incidences into the spectrometer.
