Lanthanum gallium silicate (La₃Ga₅SiO₁₄, LGS) kristale ke ea tripartite crystal system, sehlopha sa lintlha 32, sehlopha sa sebaka P₃₂₁ (No.150). LGS e na le litlamorao tse ngata joalo ka piezoelectric, electro-optical, optical rotation, hape e ka sebelisoa e le lisebelisoa tsa laser ka doping. Ka 1982, Kaminskyle al. e tlaleha kholo ea likristale tsa LGS tse doped. Ka 2000, likristale tsa LGS tse bophara ba lisenthimithara tse 3 le bolelele ba 90 mm li ile tsa ntlafatsoa ke Uda le Buzanov.

LGS kristale ke sesebelisoa se setle sa piezoelectric se nang le mofuta oa seha oa mocheso oa zero. Empa ho fapana le lits'ebetso tsa piezoelectric, lisebelisoa tsa electro-optic Q-switching li hloka boleng bo phahameng ba kristale. Ka 2003, Kongle al. ka katleho e ile ea hōlisa likristale tsa LGS ntle le mefokolo e totobetseng ea macroscopic ka ho sebelisa mokhoa oa Czochralski, 'me ea fumana hore sepakapaka sa ho hōla se ama' mala oa likristale. Ba fumane likristale tsa LGS tse se nang mebala le tse bohlooho 'me ba etsa LGS ho EO Q-switch ka boholo ba 6.12 mm × 6.12 mm × 40.3 mm. Ka 2015, sehlopha se le seng sa lipatlisiso Univesithing ea Shandong se atlehile ho holisa likristale tsa LGS tse bophara ba 50 ~ 55 mm, bolelele ba 95 mm, le boima ba 1100 g ntle le liphoso tse kholo tse hlakileng.

Ka 2003, sehlopha sa lipatlisiso se boletsoeng ka holimo Univesithing ea Shandong se ile sa lumella lebone la laser hore le fete ka har'a kristale ea LGS ka makhetlo a mabeli 'me le kenyelle leqhubu la kotara ho loantša phello ea optical rotation, kahoo ba hlokomela ts'ebeliso ea phello ea optical rotation ea LGS kristale. LGS EO Q-switch ea pele e ile ea etsoa 'me ea sebelisoa ka katleho tsamaisong ea laser.

Ka 2012, Wang le al. a lokisa LGS electro-optic Q-switch e boholo ba 7 mm × 7 mm × 45 mm, mme a hlokomela tlhahiso ea 2.09 μm pulsed laser beam (520 mJ) ka har'a lebone la lebone le pompetsoeng la Cr,Tm,Ho:YAG laser system. . Ka 2013, tlhahiso ea 2.79 μm pulsed laser beam (216 mJ) e ile ea finyelloa ka lebone la flash-lamp pumped Cr, Er:YSGG laser, le bophara ba pulse 14.36 ns. Ka 2016, Mle al. o sebelisitse sesebelisoa sa 5 mm × 5 mm × 25 mm LGS EO Q ho Nd:LuVO4 laser system, ho hlokomela sekhahla sa ho pheta-pheta sa 200 kHz, e leng sekhahla se phahameng ka ho fetisisa sa ho pheta-pheta ha LGS EO Q-switched laser system e tlalehiloeng phatlalatsa hajoale.

Joaloka lisebelisoa tsa ho fetola EO Q, kristale ea LGS e na le botsitso bo botle ba mocheso le moeli o moholo oa tšenyo, 'me e ka sebetsa ka makhetlo a mangata a ho pheta-pheta. Leha ho le joalo, ho na le mathata a ’maloa: (1) Thepa e tala ea LGS kristale e theko e boima, ’me ha ho na katleho ea ho nkela gallium sebaka ka aluminium e theko e tlaase; (2) EO coefficient ea LGS e batla e le nyenyane. E le ho fokotsa matla a ho sebetsa sebakeng sa ho netefatsa hore ho na le sebaka se lekaneng sa ho koala, bolelele ba kristale ba sesebelisoa bo hloka ho eketseha ka mokhoa oa linearly, e leng ho sa eketseng litšenyehelo feela empa hape ho eketsa tahlehelo ea ho kenya.
