LGS substrate
wehewehe
Hiki ke hoʻohana ʻia ʻo LGS e hana i nā mea piezoelectric a me electro-optical.Loaʻa iā ia nā waiwai piezoelectric kiʻekiʻe.ʻO ka coefficient hoʻohui electromechanical ʻekolu manawa o ka quartz, a ʻoi aku ka kiʻekiʻe o ka mahana hoʻololi o ka pae (mai ka lumi wela a hiki i ka helu heheʻe 1470 ℃).Hiki ke hoʻohana ʻia i ka ʻike, BAW, ka ʻike wela kiʻekiʻe a me ka mana kiʻekiʻe, kiʻekiʻe repetition rate electro-optic Q-switch.

ʻO ka wehewehe ʻana o LGS substrate
ʻO LGS (Lithium Gallium Silicate) substrate e pili ana i kahi ʻano mea pani i hoʻohana mau ʻia no ka ulu ʻana o nā kiʻiʻoniʻoni lahilahi aniani.Hoʻohana nui ʻia nā substrates LGS i nā kahua o nā mea electro-optic a me acousto-optic, e like me nā mea hoʻololi pinepine, nā modulators optical, nā mea hawewe acoustic surface, etc.
ʻO nā substrates LGS he lithium, gallium, a me nā ion silicate me nā hale aniani kikoʻī.Hāʻawi kēia haku mele ʻokoʻa i nā substrates LGS kūpono kūpono a me nā waiwai kino no nā noi like ʻole.Hōʻike kēia mau substrates i nā helu refractive kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ke aniani maikaʻi loa i ka ʻike ʻike ʻia a kokoke-infrared.
He kūpono loa nā substrate LGS no ka ulu ʻana o nā hale kiʻiʻoniʻoni lahilahi no ka mea ua kūpono lākou me nā ʻenehana deposition like ʻole e like me ka molecular beam epitaxy (MBE) a i ʻole nā ʻano ulu epitaxial e like me ka chemical vapor deposition (CVD).
ʻO nā waiwai kikoʻī o nā substrates LGS, e like me nā piezoelectric a me nā waiwai electro-optic, e hoʻolilo iā lākou i mea kūpono no ka hana ʻana i nā mea pono e koi ai i nā waiwai optical-controlled a i ʻole e hoʻohua i nā nalu acoustic surface.
I ka hōʻuluʻulu ʻana, ʻo nā substrate LGS kahi ʻano kikoʻī o nā mea substrate i hoʻohana ʻia no ka ulu ʻana i nā kiʻi ʻoniʻoni lahilahi-crystal no nā noi i nā mea electro-optic a me acousto-optic.Loaʻa i kēia mau substrates nā hiʻohiʻona optical a me ke kino i kūpono iā lākou no nā ʻano ʻano optical a me nā noi uila.
