Reconstruction of Femtosecond Laser Pulses from FROG Traces by Convolutional Neural Networks

Reconstruction of Femtosecond Laser Pulses from FROG Traces by Convolutional Neural Networks

We report on the reconstruction of ultrashort laser pulses from computer-simulated and experimental second harmonic generation-frequency resolved optical gating (SHG-FROG) spectrograms. In order to retrieve the spectral amplitude and phase we use a convolutional neural network trained on simulated S...
