Semiconductor THz Crystal: ZnTe (Zinc Telluride) kristu ifite <110> icyerekezo ikoreshwa kubisekuru bya THz muburyo bwo gukosora optique.Gukosora neza ni itandukaniro ryibihe byinshi mubitangazamakuru hamwe na kabiri ya kabiri byoroshye.Kuri femtosekond laser pulses ifite umurongo mugari ibice byinshyi bikorana kandi itandukaniro ryabyo ritanga umurongo kuva kuri 0 kugeza kuri THz nyinshi.Kumenyekanisha impanuka ya THz ibaho binyuze mumwanya wubusa-electro-optique gutahura mubindi <110> byerekanwe na ZnTe kristu.THz pulse hamwe nimpiswi igaragara ikwirakwizwa muburyo bwa kristu ya ZnTe.THz pulse itera birefringence muri kristu ya ZnTe isomwa numurongo ugizwe na polarize igaragara.Iyo byombi bigaragara impiswi na THz pulse ziri muri kristu icyarimwe, polarisiyasi igaragara izunguruka na THz pulse.Ukoresheje umurongo wa λ / 4 hamwe na polarizer yerekana urumuri hamwe na fotodi iringaniye, birashoboka gushushanya amplitude ya THz pulse ukurikiranira hafi kuzunguruka kwa pulse polarisiyonike nyuma ya kirisitu ya ZnTe mugihe gitandukanye cyo gutinda kubijyanye na THz pulse.Ubushobozi bwo gusoma amashanyarazi yuzuye, byombi amplitude no gutinda, nikimwe mubintu bikurura ibihe-domaine THz spectroscopy.ZnTe nayo ikoreshwa kubikoresho bya IR optique substrates hamwe no kubika vacuum.
