Ikristale yeZnTe

I-Semiconductor THz Crystals: I-ZnTe (i-Zinc Telluride) i-crystals ene- <110> i-orientation isetyenziselwa ukuveliswa kwe-THz ngenkqubo yokulungiswa kwe-optical.Ukulungiswa kwe-Optical ngumahluko owenziwe rhoqo kwimidiya kunye nokuchaphazeleka komyalelo wesibini.Kwi-femtosecond laser pulses ene-bandwidth enkulu amacandelo e-frequency asebenzisana kunye kwaye umahluko wabo uvelisa i-bandwidth ukusuka kwi-0 ukuya kwi-THz ezininzi.Ukufunyanwa kwe-THz pulse kwenzeka nge-free-space ye-electro-optic ukufunyanwa kwenye <110> i-crystal ye-ZnTe ejoliswe kuyo.I-THz pulse kunye ne-pulse ebonakalayo isasazwa nge-collinear nge-crystal ye-ZnTe.I-THz pulse yenza i-birefringence kwi-crystal ye-ZnTe efundwa yi-pulse ebonakalayo ehambelanayo.Xa zombini i-pulse ebonakalayo kunye ne-THz pulse i-crystal ngexesha elifanayo, i-polarization ebonakalayo iya kujikelezwa yi-THz pulse.Ukusebenzisa i-λ/4 i-waveplate kunye ne-beamsplitting polarizer kunye nesethi ye-photodiodes elinganayo, kunokwenzeka ukwenza imephu ye-THz pulse amplitude ngokubeka iliso ukujikeleza kwe-pulse polarization emva kwe-crystal ye-ZnTe ngamaxesha ahlukeneyo okulibaziseka ngokubhekiselele kwi-pulse ye-THz.Ukukwazi ukufunda intsimi yombane epheleleyo, zombini i-amplitude kunye nokulibaziseka, yenye yezinto ezikhangayo ze-time-domain THz spectroscopy.I-ZnTe ikwasetyenziselwa i-IR ye-optical components substrates kunye ne-vacuum deposition.
