Iikristale zeGGG

IGallium Gadolinium Garnet (Gd3Ga5O12okanye GGG) ikristale enye iyinto ebambekayo, esebenza ngoomatshini kunye neepropathi ezishushu ezenza ukuba ithembise ukusetyenziswa ekwenziweni kwezinto ezahlukeneyo zamehlo kunye nesubstrate imathiriyeli yeefilimu zemagneto-optical kunye nobushushu obuphezulu. i-infrared optical isolator (i-1.3 kunye ne-1.5um), eyona sixhobo esibaluleke kakhulu kunxibelelwano lwe-optical.

    Imilinganiselo yobugcisa

    I-Gallium Gadolinium Garnet (Gd3Ga5O12 okanye GGG) ikristale enye iyinto ebambekayo eneempawu ezintle zokubona, oomatshini kunye ne-thermal eyenza ukuba ibe nethemba lokusetyenziswa ekwenzeni izinto ezahlukeneyo zamehlo kunye nemathiriyeli engaphantsi kweefilimu zemagneto-optical kunye nobushushu obuphezulu be-superconductors. eyona nto ilungileyo ye-substrate ye-infrared optical isolator (1.3 kunye ne-1.5um), eyona sixhobo esibaluleke kakhulu kunxibelelwano lwe-optical.Yenziwe ngefilimu ye-YIG okanye ye-BIG kwi-substrate ye-GGG kunye neendawo ezidibeneyo.Kwakhona i-GGG yi-substrate ebalulekileyo ye-microwave isolator kunye nezinye izixhobo.Iimpawu zayo zomzimba, oomatshini kunye neekhemikhali zonke zilungile kwezi zicelo zingentla.

    Usetyenziso oluphambili:
    Imilinganiselo emikhulu, ukusuka kwi-2.8 ukuya kwi-76mm.
    Ilahleko yamehlo ephantsi (<0.1%/cm)
    Ukuhanjiswa kwe-thermal ephezulu (7.4W m-1K-1).
    Umda womonakalo welaser ophezulu (> 1GW/cm2)

    Iimpawu eziphambili:

    Ifomula yeMichiza Gd3Ga5O12
    Iparamitha yeLattic a=12.376Å
