The THz pulse of a few picosecond durations have been generated and detected via optical rectification and electro-optic effect within the same ZnTe crystal.An unbalanced single-shot detection scheme was performed to Angel Food Cake Pans characterize the signal.As a result, a multicycle signal was obtained, in which two-photon absorption and other associated nonlinear effects were reportedly negligible.The experimental set-up is compact, economical, easy to build and has Medicine the added simplicity of facilitating an independent analysis of the horizontal or vertical polarization arm of the THz-modulated chirped probe beam.
This work finds a useful application in integrated THz devices, narrow-band THz phonon spectroscopy and spectroscopic investigation of fast-occurring processes.
