Gawo la LGS
Kufotokozera
LGS ikhoza kugwiritsidwa ntchito kupanga zida za piezoelectric ndi electro-optical.Ili ndi kutentha kwakukulu kwa piezoelectric.The electromechanical coupling coefficient ndi katatu ya quartz, ndipo kutentha kwa gawoli kumakhala kwakukulu (kuchokera ku firiji kupita kumalo osungunuka 1470 ℃).Itha kugwiritsidwa ntchito mu macheka, BAW, sensor yotentha kwambiri komanso mphamvu yayikulu, kubwereza kubwereza kwa electro-optic Q-switch.

Tanthauzo la LGS Substrate
Gawo laling'ono la LGS (Lithium Gallium Silicate) limatanthawuza mtundu wina wa zinthu zomwe zimagwiritsidwa ntchito popanga mafilimu ochepa kwambiri a galasi.Magawo a LGS amagwiritsidwa ntchito kwambiri pazida za electro-optic ndi acousto-optic, monga ma frequency converters, ma modulator owoneka bwino, zida zapamadzi zamawu acoustic, ndi zina zambiri.
Magawo a LGS amakhala ndi lithiamu, gallium, ndi ma ion silicate okhala ndi mawonekedwe apadera a kristalo.Kuphatikizika kwapaderaku kumapereka magawo a LGS owoneka bwino komanso owoneka bwino pazogwiritsa ntchito zosiyanasiyana.Magawo ang'onoang'onowa amawonetsa mawonekedwe owoneka bwino, kuyamwa kowala pang'ono, komanso kuwonekera bwino kwambiri pamawonekedwe apafupi ndi mafunde amtundu wa infrared.
Magawo a LGS ndi oyenera makamaka kukula kwa mawonekedwe a filimu woonda chifukwa amagwirizana ndi njira zosiyanasiyana zoyikamo monga molecular beam epitaxy (MBE) kapena njira zokulirapo za epitaxial monga chemical vapor deposition (CVD).
Zodziwika bwino za magawo a LGS, monga piezoelectric ndi electro-optic properties, zimawapangitsa kukhala abwino popanga zida zomwe zimafunikira mawonekedwe owongolera ma voltage kapena kupanga mafunde apamtunda.
Mwachidule, magawo a LGS ndi mtundu wina wa zinthu zomwe zimagwiritsidwa ntchito popanga mafilimu ochepa kwambiri a kristalo omwe amagwiritsidwa ntchito pazida za electro-optic ndi acousto-optic.Magawo awa ali ndi mawonekedwe owoneka bwino komanso owoneka bwino omwe amawapangitsa kukhala oyenera kugwiritsa ntchito mawonekedwe osiyanasiyana amagetsi ndi zamagetsi.
