1) The THz detection range is reported for a 50 fs pulse width at 800 nm with 1 mm or 0.2 mm thick ZnTe wafers serving as EO crystal. The range is limited by pulse duration, averaging time, EO crystal , EO crystal thickness, and laser noise. User can replace EO crystal to increase bandwidth at the cost of signal intensity.

2) The THz resolution is limited by the total time scanned, which is set by the maximum THz gate delay. Commonly, detection of the THz waveform after >150 ps is often limited by noise.

3) Derived units are for the pump delay stage. Recommended maximum acceleration is reduced with added mass for 8-pass option.
