Substrate LGS
Sharaxaada
LGS waxaa loo isticmaali karaa in lagu sameeyo aaladaha piezoelectric iyo electro-optical.Waxay leedahay sifooyinka piezoelectric heerkulka sare.Isku xidhka koronto-mechanical coefficient waa saddex jeer ka quartz, iyo heerkulbeegga marxaladda kala guurka waa sare (laga bilaabo heerkulka qolka ilaa barta dhalaalay 1470 ℃).Waxaa loo isticmaali karaa miinshaarta, BAW, dareeme heerkulka sare iyo awood sare, celceliska sare ee heerka koronto-optic Q-switch.

Qeexida Substrate-ka LGS
Substrate LGS (Lithium Gallium Silicate) waxa loola jeedaa nooc gaar ah oo ka samaysan substrate sida caadiga ah loo isticmaalo korriinka filimada khafiifka ah ee hal crystal ah.Substrate-yada LGS waxaa inta badan loo adeegsadaa dhinacyada korantada-optic-ga iyo aaladaha acousto-optic, sida beddelayaasha soo noqnoqda, modulators indhaha, aaladaha mowjadaha dhawaaqa korka, iwm.
Qaybaha LGS waxay ka kooban yihiin lithium, gallium, iyo ion silicate oo leh dhismayaal crystal gaar ah.Halabuurkan gaarka ah wuxuu siinayaa substrates LGS guryaha ugu fiican ee muuqaal iyo muuqaal ah oo loogu talagalay codsiyo kala duwan.Substrates-yadani waxay muujinayaan tusmooyin dib-u-celin aad u sarreeya, nuugista iftiinka hooseeya, iyo hufnaan aad u wanaagsan oo muuqda ilaa baaxadda hirarka dhererka infrared-ka.
Qaybaha LGS waxay si gaar ah ugu habboon yihiin koritaanka qaababka filimada khafiifka ah maadaama ay ku habboon yihiin farsamooyinka kala duwan ee kaydinta sida molecular beam epitaxy (MBE) ama hababka koritaanka epitaxial sida kaydinta uumiga kiimikada (CVD).
Tilmaamaha gaarka ah ee substrates LGS, sida piezoelectric iyo guryaha electro-optic, waxay ka dhigaan kuwo ku haboon qalabka wax soo saarka ee u baahan sifooyinka indhaha ee korantada lagu xakameeyo ama dhaliya hirarka dhawaaqa sare.
Marka la soo koobo, substrates LGS waa nooc gaar ah oo ka mid ah walxaha substrate loo isticmaalo in lagu beero filimo khafiif ah oo hal-crystal ah oo loogu talagalay codsiyada qalabka korantada iyo acousto-optic.Substrates-yadani waxay leeyihiin astaamo muuqaal iyo muuqaal muuqaal ah oo ka dhigaya inay ku habboon yihiin codsiyada indhaha iyo elektiroonigga ah ee kala duwan.
