Abstract

Next generation THz applications require specially tailored THz pulses. Systems that use optical rectification in crystals as their THz source are susceptible to changes in the pulse envelope. Our feedback-loop system designed around a pulse shaper with a liquid crystal mask can shape the phase and amplitude of the excitation pulse and optimize the shape of the emitted THz waveform. This is demonstrated using as an example the creation of single-cycle THz pulses.
