ZnTe Crystal

Semiconductor THz Crystals: Hoʻohana ʻia nā kristal ZnTe (Zinc Telluride) me ka <110> orientation no ka hana THz ma ke kaʻina hana hoʻoponopono.ʻO ka hoʻoponopono ʻana i ka Optical he ʻokoʻa ka hoʻomohala pinepine ʻana i ka media me ka nui o ke kauoha lua.No nā pulse laser femtosecond nona ka bandwidth nui e pili ana nā ʻāpana alapine i kekahi i kekahi a ʻo kā lākou ʻokoʻa e hana i ka bandwidth mai 0 a i kekahi mau THz.Loaʻa ka ʻike ʻana i ka pulse THz ma o ka ʻike electro-optic kaʻawale i loko o kahi aniani ʻē aʻe <110> ZnTe.Hoʻolaha pū ʻia ka pulse THz a me ka pulse ʻike ʻia ma o ke aniani ZnTe.Hoʻoulu ka THz pulse i ka birefringence ma ZnTe kristal i heluhelu ʻia e kahi pulse ʻike ʻia polarly.I ka manawa like ka pulse ʻike ʻia a me ka pulse THz i ka manawa like, e hoʻohuli ʻia ka polarization ʻike ʻia e ka pulse THz.Ke hoʻohana nei i ka waveplate λ/4 a me ka beamsplitting polarizer me kahi pūʻulu o nā photodiodes kaulike, hiki ke palapala ʻia i ka THz pulse amplitude ma ka nānā ʻana i ka huli ʻana o ka pulse polarization ʻike ʻia ma hope o ke aniani ZnTe i nā manawa lohi e pili ana i ka pulse THz.ʻO ka hiki ke heluhelu i ke kahua uila piha, ka amplitude a me ka lohi, ʻo ia kekahi o nā hiʻohiʻona nani o ka spectroscopy THz domain-time.Hoʻohana pū ʻia ʻo ZnTe no nā substrates opioptical IR a me ka waiho ʻana o ka vacuum.
