In this paper, we propose and experimentally demonstrate noncollinear EO sampling of terahertz pulses with a femtosecond fiber laser in cm-thick GaAs crystals. This technique provides more than an order of magnitude improvement in spectral resolution and a significant increase in efficiency as compared to previously used collinear EO sampling in mm- and sub-mm-thick GaAs crystals.
