Crystals GGG

Gallium Gadolinium Garnet (Gd3Ga5O12 ama GGG) hal crystal waa walxo leh muuqaal wanaagsan, farsamo iyo kuleyl taas oo ka dhigaysa mid rajo u leh in loo isticmaalo samaynta qaybaha kala duwan ee indhaha iyo sidoo kale walxaha substrate ee filimada magneto-optical iyo heerkul sare. Maaddada substrate-ka ugu fiican ee go'doominta indhaha infrared (1.3 iyo 1.5um), oo ah aalad aad muhiim u ah isgaarsiinta indhaha.Waxay ka samaysan tahay YIG ama filim BIG ah oo ku yaal substrate GGG oo lagu daray qaybo birefringence ah.Sidoo kale GGG waa substrate muhiim u ah go'doominta microwave iyo aaladaha kale.Sifooyinkeeda jidheed, makaanikada iyo kiimikaad ayaa dhamaantood u fiican codsiyada kor ku xusan.

Codsiyada ugu muhiimsan:
Cabirrada waaweyn, laga bilaabo 2.8 ilaa 76mm.
Khasaaraha indhaha oo hooseeya (<0.1%/cm)
Dhaqdhaqaaqa kulaylka sare (7.4W m-1K-1).
Heerka waxyeelada laysarka sare (> 1GW/cm2)
