    Izakhiwo eziyisisekelo

    Nd: I-YAP AlO3 perovskite (YAP) ingumbungazi owaziwayo wama-lasers wombuso oqinile. I-crystal anisotropy ye-YAP inikeza izinzuzo eziningi.Ivumela ukuhlelwa okuncane kwe-wavelength ngokushintshashintsha isiqondisi se-wave vector ku-crystal. Ngaphezu kwalokho, ugongolo lokukhipha luhlukaniswe ngomugqa.
    Izinzuzo ze-Nd: Amakristalu we-YAP:
    Umkhawulo ongaqhathaniswa nokusebenza kahle kwethambeka ku-1079nm kuye ku-Nd: YAG ku-1064nm
    Ukusebenza kahle okuphezulu ku-1340nm kuqhathaniswa no-Nd: YAG e-1319nm
    Umugqa wokukhipha umugqa ohlukanisiwe 
    Ukumuncwa okuphezulu emanzini nasemanzini omzimba we-1340nm kuqhathaniswa ne-1319nm
