LGS Substrate
Tlhaloso
LGS e ka sebelisoa ho etsa lisebelisoa tsa piezoelectric le electro-optical.E na le litšobotsi tse phahameng tsa mocheso oa piezoelectric.The electromechanical coupling coefficient ke makhetlo a mararo ho feta a quartz, 'me mocheso oa phetoho ea mohato o phahame (ho tloha mocheso oa kamore ho ea ho melting point 1470 ℃).E ka sebelisoa ho sakha, BAW, sensor ea mocheso o phahameng le matla a phahameng, sekhahla se phahameng sa ho pheta-pheta electro-optic Q-switch.

Tlhaloso ea LGS Substrate
LGS (Lithium Gallium Silicate) substrate e bua ka mofuta o itseng oa thepa ea substrate e atisang ho sebelisoa bakeng sa kholo ea lifilimi tse tšesaane tsa kristale e le 'ngoe.Li-substrates tsa LGS li sebelisoa haholo-holo masimong a lisebelisoa tsa electro-optic le acousto-optic, joalo ka li-converter tsa maqhubu, li-modulators tsa optical, lisebelisoa tsa maqhubu a maqhubu a holimo, jj.
Li-substrates tsa LGS li na le li-ion tsa lithium, gallium le silicate tse nang le meaho e khethehileng ea kristale.Sebopeho sena se ikhethileng se fana ka likaroloana tsa LGS tse ntle tsa optical le 'mele bakeng sa lits'ebetso tse fapaneng.Li-substrates tsena li bonts'a li-indices tse batlang li na le refractive, ho monyeha ha leseli le tlase, le pepeneneng e ntle haholo sebakeng se bonahalang ho isa haufi le leqhubu la maqhubu a leholimo.
Li-substrates tsa LGS li loketse ka ho khetheha bakeng sa kholo ea libopeho tse tšesaane tsa filimi kaha li lumellana le mekhoa e fapaneng ea ho beha lintho tse kang molecular beam epitaxy (MBE) kapa mekhoa ea ho hōla ha epitaxial e kang chemical vapor deposition (CVD).
Mehaho e khethehileng ea li-substrates tsa LGS, tse kang piezoelectric le electro-optic properties, li etsa hore e be tse loketseng bakeng sa ho etsa lisebelisoa tse hlokang lisebelisoa tsa optical tse laoloang ke voltage kapa ho hlahisa maqhubu a holimo a acoustic.
Ka kakaretso, li-substrates tsa LGS ke mofuta o itseng oa thepa ea substrate e sebelisetsoang ho hōlisa lifilimi tse tšesaane tsa kristale e le 'ngoe bakeng sa lisebelisoa tsa electro-optic le acousto-optic.Li-substrates tsena li na le thepa e lakatsehang ea optical le ea 'mele e etsang hore e tšoanelehe bakeng sa lisebelisoa tse fapaneng tsa optical le elektroniki.
