    Nga taonga taketake

    Nd: Ko te YAP AlO3 perovskite (YAP) he kaihautu rongonui mo nga lasers state solid. Ko te anisotropy karaihe o te YAP he maha nga painga. Ka whakaaehia he whakarereke iti o te roangaru ma te rereke i te ahunga rererangi ngaru i roto i te karaihe. Ano hoki, ko te kurupae whakaputa he mea whakamarumaru.
    Nga Painga o Nd: Tioata YAP:
    Paepae whakataurite me te kakama o te pari i te 1079nm ki te Nd: YAG i te 1064nm
    Te kaha ake i te 1340nm i whakaritea ki a Nd: YAG i te 1319nm
    He raima whakaputa polarized 
    Te kaha o te ngongo ki te wai me te waipiro o te tinana 1340nm i te 1319nm
