Nd: YAG Crystal
Nd: YAG (Neodimium Doped Yttrium Aluminum Garnet) kua tiimata me te haere tonu hei karaihe laser e whakamahia whānuitia ana mo nga kaimaratae totika. Mo te oranga whanui pai (e rua nga wa atu i tera o Nd: YVO4) me te kawenga parawene, me te ao pakari, hanga ko te tihi: YAG he karaihe tino pai mo te ngaru kaha tonu te kaha, te kaha o te Q-hurihuri me te aratau kotahi.
E whakarato ana a WISOPTIC ki a Nd: YAG raka me nga ahuatanga e whai ake nei: he rereke nga reko rekoataa, te homogeneity teitei teitei, he tika te tukatuka, he miihini hanga tika me te koki poro, he maha nga tapahi mutunga, he maha nga korepu dielectric, te paepae kino kino.
Whakauru mai ki a maatau mo te otinga tino pai mo to tono a Nd: nga karaati YAG.
