Description

A Rubidium Titanyl Phosphate (RTP) Pockels cell was placed in an optical transverse configuration in line with a fast modulation high voltage source. Two crossed polarizers were configured to allow light through the system during a voltage pulse across the Pockels cell. Sources of additive noise were identified with power spectrum analysis. Noise power in the active pulse was measured to be 3.412*10^-15 (V^2/sqrt(Hz)). Accounting for this noise and digital signal filtering, timing information of the active pulse was captured. A rise time of 15.94 ± 0.416 (ns) with a recovery time of 1.39 ± 0.072 (μs) was demonstrated using our setup. The measured pulse width was stable about 1.37 ± 0.016 (μs).
