    Cov khoom yooj yim

    Nd: YAP AlO3 perovskite (YAP) yog tus tswv tsev paub txog lub xeev lasers. Lub tsom iav anisotropy ntawm YAP muaj ntau qhov zoo heev.Nws tso cai me me hloov ntawm yoj yoj los ntawm kev hloov raws yoj vector kev taw qhia nyob rau hauv cov siv lead ua. Ntxiv mus, cov kab tawm tau tawm yog linearly polarized.
    Zoo ntawm Nd: YAP Muaju:
    Tau piv rau qhov pib thiab nqes hav efficiency ntawm 1079nm rau Nd: YAG ntawm 1064nm
    Kev ua haujlwm siab ntau dua ntawm 1340nm piv rau Nd: YAG ntawm 1319nm
    Linearly polarized tso tawm nqaj 
    Kev nqus tau ntau dua hauv cov dej thiab lub cev ntawm 1340nm piv rau 1319nm
