ʻO ka lepo ʻo TeO2
wehewehe
ʻO ke aniani ʻo TeO2 kahi ʻano mea acoustooptic me ke kumu kiʻekiʻe.Loaʻa iā ia ka birefringence maikaʻi a me ka hoʻololi ʻana i ka optical rotation, a ua lohi ka wikiwiki o ke kani ʻana ma ke ala o [110];inā hiki ke hoʻomaikaʻi ʻia ka hoʻonā ʻana o ka mea acoustooptic i hana ʻia me TeO2 single crystal e kahi kauoha o ka nui ma lalo o ka puka like, wikiwiki ka pane pane, liʻiliʻi ka mana hoʻokele, kiʻekiʻe ka pono diffraction, a kūpaʻa ka hana. .

ʻO ka wehewehe ʻana o TeO2 substrate
ʻO ka substrate TeO2 (tellurium dioxide) e pili ana i kahi mea crystalline i hoʻohana mau ʻia i nā noi like ʻole e pili ana i ka optics, optoelectronics a me acoustics.Eia kekahi mau mea nui e pili ana i nā substrates TeO2:
1. Ka hoʻoheheʻe ʻana o ke aniani: ʻO TeO2 he ʻano aniani tetragonal, a ua hoʻonohonoho ʻia nā ʻātoma tellurium a me ka oxygen i loko o kahi lattice ʻekolu.Aia ia i ka ʻōnaehana kristal orthorhombic.
2. ʻO nā hiʻohiʻona acousto-optic: Ua kaulana ʻo TeO2 no kāna mau hiʻohiʻona acousto-optic maikaʻi loa, a ua kūpono i nā mea acousto-optic e like me nā modulators, deflectors, a me nā kānana tunable.Ke hele nā hawewe kani i loko o kahi aniani TeO2, hoʻololi ia i ka ʻōlelo kuhikuhi refractive, e hoʻololi a hoʻomalu paha i ke ala o ka mālamalama e hele ai.
3. Ka laulā ākea o ke aniani: He ākea ākea ka TeO2, mai kahi kokoke i ka ultraviolet (UV) a i nā ʻāpana waena-infrared (IR).Hiki iā ia ke hoʻouna i ka mālamalama mai kahi o 0.35 μm a i 5 μm, hiki ke hoʻohana i ka hoʻohana ʻana i kahi ʻano o nā mea optical a me nā noi.
4. ʻO ka wikiwiki kani kiʻekiʻe: He kiʻekiʻe ka wikiwiki o TeO2,ʻo ia hoʻi, hiki iā ia ke hoʻolaha maikaʻi i nā hawewe kani ma o ke aniani.He mea koʻikoʻi kēia waiwai no ka ʻike ʻana i nā mea hana acousto-optic kiʻekiʻe me nā manawa pane wikiwiki.
5. Nā waiwai ʻike ʻole linear: Hōʻike ʻo TeO2 i nā waiwai optical nonlinear nui.Hiki iā ia ke hana i nā alapine hou a hoʻololi paha i nā waiwai o ka mālamalama hanana ma o ka launa pū ʻole.Ua hoʻohana ʻia kēia waiwai i ka hoʻololi ʻana i ka nalu nalu a me nā noi pālua pinepine.
6. Nā waiwai Thermodynamic: Loaʻa iā TeO2 ke kūpaʻa wela maikaʻi a me ka ikaika mechanical, hiki iā ia ke mālama i kona mau waiwai ma luna o kahi ākea ākea a kū i ke koʻikoʻi mechanical me ka ʻole o ka deformation a i ʻole degradation nui.He mea kūpono kēia no nā mea mana acousto-optic kiʻekiʻe.
7. Paʻa kemika: He kūpaʻa kemika ʻo TeO2 a kūpaʻa i nā solvents maʻamau a me nā waikawa, e hōʻoiaʻiʻo ana i kona kūpaʻa a me ka hilinaʻi ma lalo o nā ʻano hana like ʻole a me nā kaiapuni.
Hoʻohana nui ʻia nā substrates TeO2 i nā noi e like me acousto-optic modulators, deflectors, tunable filters, optical switch, frequency shifters, a me nā ʻōnaehana hoʻokele kukuna laser.Hoʻohui ia i nā waiwai optic acousto-optic a me nonlinear optical, ākea ākea ākea, thermal maikaʻi a me ka mechanical stability, a me ke kūpaʻa kemika, e lilo ia i mea versatile i nā optics a me optoelectronics.
