Er: YAG –Egqwesileyo 2.94 um Laser Crystal
Ingcaciso yeMveliso
Lo msebenzi uphonononga izalathisi kunye nobuchule beEre: YAGi-laser skin resurfacing kwaye iqaqambisa indima yeqela leengcali ekuvavanyeni nasekunyangeni izigulana eziye zenziwa i-Er: YAG laser resurfacing yolusu.
Er: YAG luhlobo olugqwesileyo lwe-2.94 um laser crystal, esetyenziswa ngokubanzi kwinkqubo yonyango ye-laser kunye neminye imimandla.Er: YAGI-crystal laser yeyona nto ibalulekileyo ye-laser ye-3nm, kunye ne-slope enokusebenza okuphezulu, inokusebenza kwi-laser yeqondo lokushisa, i-laser wavelength ingaphakathi komda webhendi yokhuseleko lwamehlo abantu, njl.
2.94 umEr: YAGi-laser isetyenziswe ngokubanzi kunyango lwezonyango, ubuhle besikhumba, unyango lwamazinyo.I-Lasers exhaswe ngu-Er: YAG (i-erbium ithathelwe indawo: i-yttrium aluminium garnet), esebenza kwi-2.94 microns, i-crystals isibini kakuhle emanzini kunye namanzi omzimba. Oku kuluncedo kakhulu kwizicelo kwiinkalo zonyango lwe-laser kunye nonyango lwamazinyo. Imveliso ye-Er:YAG yenza ukuba kujongwe ngokungenazintlungu kumanqanaba eswekile yegazi, ngelixa inciphisa ngokukhuselekileyo umngcipheko wosulelo. Ikwasebenza kunyango lwe-laser lwezicubu ezithambileyo, ezinje nge-cosmetic resurfacing. Iluncedo ngokulinganayo ekuphatheni izicubu eziqinileyo ezifana ne-enamel yezinyo.
Er:YAG yonwabela i-advanteji ngaphezu kwezinye iikristale zelaser kuluhlu lwe-2.94 micron kuba isebenzisa i-YAG njengomamkeli crystal. Izinto ezibonakalayo, ezishushu kunye nezamehlo ze-YAG zaziwa ngokubanzi kwaye ziqondwa kakuhle. Abaqulunqi beLaser kunye nabaqhubi banokusebenzisa ubunzulu babo bamava kunye ne-Nd: YAG iinkqubo ze-laser ukuphumeza ukusebenza okuphezulu ukusuka kwiinkqubo ze-2.94 micron laser usebenzisa i-Er: YAG.
