    Vhidhiyo

    Nd: YAG kristaro tsvimbo inoshandiswa muLatin yekumaka muchina uye mimwe michina ye laser. 
    Iyo chete ndiyo yakasimba zvinhu iyo inogona kushanda inoenderera firiji yemukati, uye ndiyo yakanyanya kunaka kuita laser kristaro.
    Zvakare, iyo YAG (yttrium aluminium garnet) laser inogona kudhonzwa ne chromium uye neodymium kuitira kusimudzira hunhu hwekudyiwa kweiyo laser. Nd, Cr: YAG laser yakasimba solid laser .Chomi yeChromium (Cr3 +) ine yakadzika yekumwa bhendi; inobata simba uye yoiendesa kune neodymium ions (Nd3 +) nenzira yekudyidzana kwedipole-dipole.Wavelength ye1064nm inoburitswa neiyi laser.
    Iyo laser chiito chaNd: YAG laser yakatanga kuratidzwa paBell Laboratories mugore ra1964.Nd, Cr: YAG laser inopomberwa nemwenje wezuva.Nekuita doping ne chromium, simba rekutora simba re laser rinowedzerwa uye Ultra mapfupi mafuru anoburitswa.
