    Zida zoyambira

    La3Ga5SiO14 kristalo (LGS crystal) ndichinthu chopanda mawonekedwe chowoneka bwino chokhala ndi chiwonongeko chachikulu, magwiridwe antchito okwanira kwamagetsi komanso magwiridwe antchito abwino kwambiri. Kristalo ya LGS ndi ya dongosolo la trigonal dongosolo, koyefitima kakang'ono kowonjezera kwamatenthedwe, kukhathamiritsa kwamatenthedwe kristalo ndi kofooka, kutentha kwa kutentha kwambiri ndikwabwino (kuposa SiO2), yokhala ndi ma coefficients awiri odziyimira pawokha ndiabwino ngati a BBO Makhiristo. Ma coefficients a electro-optic amakhala osasunthika pamitundumitundu. Kristalo ili ndi mawonekedwe abwino, osadumphadumpha mphamvu, osapatsa mphamvu, okhazikika pamafizikiki ndipo ali ndi magwiridwe antchito abwino kwambiri. Kristalo ya LGS ili ndi gulu lofalitsira lonse, kuyambira 242nm-3550nm ili ndi chiwopsezo chambiri. Itha kugwiritsidwa ntchito pakusinthira kwa EO ndi EO Q-Switches.

    Kristalo ya LGS imagwiritsa ntchito mitundu ingapo: kuphatikiza mphamvu yama piezoelectric, kuwala kwa kasinthasintha, magwiridwe ake a electro-optical amachitanso bwino kwambiri, Maselo a LGS Pockels amakhala ndi kubwereza kwapafupipafupi, kutsegula kwa gawo lalikulu, kupindika kozungulira, mphamvu yayikulu, kopitilira muyeso Kutentha kotsika ndi zina ndizoyenera LGS crystal EO Q -switch. Tidagwiritsa ntchito kuchuluka kwa EO kwa γ 11 kupanga ma LG Pockels cell, ndikusankha kuchuluka kwake kwakukulu kuti muchepetse mphamvu yamagetsi yama cell a LGS Electro-Optical, yomwe itha kukhala yoyenera kuyika kwa electro-optical of all- Solid state laser wokhala ndi kubwerezabwereza kwamphamvu kwamphamvu. Mwachitsanzo, itha kugwiritsidwa ntchito ku LD Nd: YVO4 laser yolimba yampopopedwa ndimphamvu yayikulu ndi mphamvu zoposa 100W, ndipamwamba kwambiri mpaka 200KHZ, zotulutsa zabwino kwambiri mpaka 715w, kutentha kwake mpaka 46ns, mosalekeza Kutulutsa mpaka pafupifupi 10w, ndipo mawonekedwe owonongeka akuwonjezeka nthawi 9-10 kuposa LiNbO3 crystal. 1/2 wave wave ndi 1/4 wave voltage ndiotsika poyerekeza ndi ma cell ofanana a BBO Pockels, ndipo mtengo wake ndi mtengo wake ndizotsika poyerekeza ndi ma cell a RTP Pockels Maselo. Poyerekeza ndi Maselo a DKDP Pockels, samakhala yankho ndipo amakhala ndi kutentha kwabwino. Maselo a LGS Electro-Optical amatha kugwiritsidwa ntchito m'malo ovuta ndipo amatha kuchita bwino mosiyanasiyana.
