Er: YAG –Umwiza mwiza 2.94 Um Laser Crystal
Ibisobanuro ku bicuruzwa
Iki gikorwa gisubiramo ibimenyetso na tekinike yaEr: YAGuruhu rwa laser rwongeye kugaragara kandi rugaragaza uruhare rwitsinda ryabasobanuzi mugusuzuma no kuvura abarwayi batewe na Er: YAG laser reurfacing yuruhu.
Er: YAG ni ubwoko bwiza bwa 2.94 um laser kristal, ikoreshwa cyane muri sisitemu yubuvuzi bwa laser nizindi nzego.Er: YAGkirisiti ya kirisiti ni ikintu cyingenzi cya 3nm laser, kandi ahahanamye hamwe nubushobozi buhanitse, irashobora gukorera mubushyuhe bwicyumba cya laser, uburebure bwumurongo wa laser buri murwego rwumutekano wamaso yumuntu, nibindi.
2.94 umEr: YAGlazeri yakoreshejwe cyane mubuvuzi bwubuvuzi, ubwiza bwuruhu, kuvura amenyo.Ibikoresho bikoreshwa na Er: YAG (erbium yasimbuwe: yttrium aluminium garnet), ikora kuri microne 2,94, kristaliste neza mumazi no mumazi yumubiri.Ibi ni ingirakamaro cyane cyane mubikorwa mubijyanye nubuvuzi bwa laser nubuvuzi bw amenyo.Umusaruro wa Er: YAG ituma habaho gukurikirana ububabare bwisukari yamaraso, mugihe bigabanya neza ibyago byo kwandura.Ifite kandi akamaro kanini kuvura lazeri yoroheje, nka cosmetic resurfacing.Ningirakamaro kimwe mukuvura ingirangingo zikomeye nka amenyo yinyo.
Er.Ibintu bifatika, ubushyuhe na optique bya YAG birazwi cyane kandi birasobanutse neza.Abashushanya Laser hamwe nababikoresha barashobora gukoresha uburebure bwuburambe hamwe na Nd: YAG laser sisitemu kugirango bagere kumikorere isumba iyindi ya sisitemu ya micron laser 2.94 ukoresheje Er: YAG.
