Zinc Telluride Crystal ZnTe Crystal
Product Introduction
[110]The ZnTe (teflon) crystal with a crystalline orientation is often used to generate terahertz oscillations through optical rectification. The optical rectification effect is a second-order nonlinear effect and also a special type of difference frequency effect. A laser pulse with a certain width, which has a very wide frequency component, will interact with each other (mainly through difference frequency) to produce electromagnetic waves ranging from 0 to several terahertz.
Terahertz pulses can be optically detected through another [110] crystal orientation in zinc telluride (ZnTe). The terahertz light pulse causes the ZnTe crystal to exhibit birefringence. Therefore, when the terahertz light pulse and the visible light pulse propagate in a straight line simultaneously in the zinc telluride crystal, the polarization state of the visible light will change accordingly. Using a λ/4 wave plate, a polarization beam splitter, and a balanced photodiode, we can monitor the polarization state of the visible light and thereby obtain various parameters such as the amplitude and delay of the terahertz light pulse. This ability to monitor the complete electromagnetic field information (amplitude and phase delay) of the terahertz light pulse is one of the attractive features of the time-domain terahertz spectrometer.
