ʻEr: YAG -He Crystal Laser 2.94 Um maikaʻi loa

ʻO ka wehewehe pōkole:

ʻO ka Erbium:yttrium-aluminum-garnet (Er:YAG) ka hoʻoulu ʻana i ka ʻili laser he ʻano hana maikaʻi no ka hoʻokele liʻiliʻi a me ka hoʻokele maikaʻi ʻana i nā kūlana ʻili a me nā ʻeha. ʻO kāna mau hōʻailona nui e pili ana i ka mālama ʻana i ka photoaging, rhytids, a me nā maʻi maʻi maʻi maʻi maʻi.

Hōʻike kēia hana i nā hōʻailona a me ka ʻenehana noʻE:YAGka ʻili laser hou a hōʻike i ke kuleana o ka hui interprofessional i ka loiloi a me ka mālama ʻana i nā maʻi i hoʻopaʻa ʻia i ka Er:YAG laser resurfacing o ka ʻili.

ʻEr: ʻO YAG kahi ʻano o ka kristal laser 2.94 um maikaʻi loa, hoʻohana nui ʻia i ka ʻōnaehana lāʻau laser a me nā māla ʻē aʻe.ʻAe: YAGʻO ka laser kristal ka mea koʻikoʻi loa o ka laser 3nm, a ʻo ka slope me ka hana kiʻekiʻe, hiki ke hana i ka laser wela lumi, ʻo ka lōʻihi o ka hawewe laser i loko o ke ʻano o ka hui palekana maka kanaka, etc.

2.94 umʻAe: YAGUa hoʻohana nui ʻia ka laser i ka ʻoki ʻana i ka lāʻau lapaʻau, ka nani o ka ʻili, ka mālama ʻana i nā niho. He mea maikaʻi loa kēia no nā noi ma nā kahua o ka lāʻau lapaʻau laser a me ka dentistry. ʻO ka hoʻopuka ʻana o Er:YAG hiki i ka nānā ʻole ʻana i nā pae kō koko, ʻoiai e hōʻemi ana i ka pilikia o ka maʻi. He mea maikaʻi nō hoʻi no ka hoʻomaʻamaʻa laser i nā ʻiʻo palupalu, e like me ka resurfacing cosmetic. He pono like ia no ka mālama ʻana i ka ʻiʻo paʻakikī e like me ka enamel niho.

ʻEr: Ua hauʻoli ʻo YAG ma mua o nā kristal laser ʻē aʻe i ka pae 2.94 micron ma ka hoʻohana ʻana iā YAG ma ke ʻano he aniani hoʻokipa. ʻIke nui ʻia a hoʻomaopopo maikaʻi ʻia nā waiwai kino, thermal a optical o YAG. Hiki i nā mea hoʻolālā laser a me nā mea hoʻohana ke hoʻohana i ko lākou hohonu o ka ʻike me Nd:YAG ʻōnaehana laser e hoʻokō i ka hana ʻoi aku ka maikaʻi mai nā ʻōnaehana laser 2.94 micron me ka hoʻohana ʻana iā Er:YAG.
