    Hiki i ka YAG (yttrium alumini garnet) laser ke hoʻopili ʻia me ka chromium a me ka neodymium i mea e hoʻonui ai i nā ʻano omo o ka kukuna. ʻO ka laser NdCrYAG kahi laser paʻa paʻa. ʻO ka chromium ion (Cr3 +) kahi hui hoʻoluʻu ākea; lawe ia i ka ikehu a hoʻoili iā ia i nā iona neodymium (Nd3 +) ma o ke ʻano o ka pilina dipole-dipole. Kuhi ʻia ka lōʻihi o 1.064 µm e kēia laser.
    ʻO ka hana laser a Nd-YAG kukuna i hōʻike mua ʻia ma nā Bell Laboratories i ka makahiki 1964. Hoʻomaʻa ʻia ka laser NdCrYAG e kahi pāhawewe lā. Ma o ke kāpili ʻana me ka chromium, hoʻonui ʻia ka hiki o ka mimiki ikehu o ka laser a hoʻokuʻu ʻia nā ultra pulses pōkole.
    ʻO nā noi maʻamau o kēia laser me ka hana ʻana o nanopowders a ma ke ʻano he kumu paipu no nā kukuna ʻē aʻe. 
    Nā noi:
    ʻO ka noi mua o Nd: Cr: YAG kukuna me he kumu paipu lā. Hoʻohana ʻia ia i nā kukuna pulu ka ikehu lā, kahi e hoʻohana ʻia me he ʻōnaehana ukali lā.
    ʻO kahi noi hou o Nd: Cr: YAG kukuna i ka hana hoʻokolohua o nanopowder.
