ZnTe crystal has been a popular choice among researchers for detecting and analyzing Terahertz waves due to its high sensitivity and favorable optical properties. In this analytical study, the researchers aimed to measure the intensity of Terahertz waves generated by a Terahertz Parametric Oscillator (TPO) using a ZnTe electro-optic crystal.

The pump-probe technique was employed, where a short pump pulse (Terahertz wave) and a probe pulse (near IR laser) were made to interact in the ZnTe crystal. The interaction resulted in the electro-optical phenomena in the crystal, which was then used to measure the intensity of the Terahertz waves.

The THz pulses generated by TPO had a duration of 10-25 ns at a repetition rate of 1 Hz. The ZnTe crystal was used for intensity measurement of THz-waves. The two effects, namely Pockels effect and Kerr effect, were discussed for electro-optic sampling, and the interaction of two beams from or transmission through the ZnTe crystal was also studied.

The probe pulse intensity contains information about the THz-wave intensity, and the researchers were able to analyze the THz wave intensity using the ZnTe crystal. They found that the ZnTe crystal is highly sensitive to THz waves, and its use in electro-optic detection can facilitate the detection and analysis of Terahertz waves.

This analytical study has significant implications for the development of future Terahertz wave detection and analysis technologies. The use of ZnTe crystal in Terahertz wave detection can lead to the development of more sensitive and accurate Terahertz wave detectors, which can be useful in a wide range of applications, including security, medical diagnosis, and communication.

In conclusion, the analytical study of Terahertz wave intensity measurement using ZnTe electro-optic crystal presents a promising avenue for the detection and analysis of Terahertz waves. Its potential applications in various fields make it a valuable area of research and development, and further studies in this field can lead to the development of new technologies that can revolutionize the way we use and interact with Terahertz waves.
