Fig. 2: EOS characterization of channels CH1 and CH2.
From: Electro-optic characterization of synthesized infrared-visible light fields
The second (a) and first channel (b) have been characterized via EOS using CH0 as the sampling pulse. The Fourier transform of the time domain (c) shows that frequencies above 400 THz, and therefore in the visible range, can be field resolved via EOS. The black line indicates the spectra of the two channels measured using two spectrometers. The comparison proves that the main spectral features can be reconstructed by the EOS measurements. The gray area (c) indicates the region where the SNR is below 1.
