Spatio-temporal diagnosis of few-cycle 3.2 µm pulses from a mid-IR OPCPA system
Four-cycle pulses from a 3.2 µm OPCPA system were characterized by spatially resolved Fourier transform spectroscopy, for the first time. Combining the spatio-spectral information with temporal characterization yielded the spatio-temporal structure of the pulses revealing up to now inaccessible details in the mid-IR spectral region. The proposed technique offers efficient and simple characterization for the optimization of MIR OPCPA systems in terms of spatio-spectral couplings.
