Keywords:high-harmonic generation, deep learning, pulse characterization

We propose a new laser pulse characterization method based on deep learning. In this method, the temporal waveform of a laser pulse, including its carrier-envelope phase and absolute intensity, can be reconstructed from its high-harmonic spectrum. We numerically checked the validity of the method.
