    Nd: YAG crystal induku isetshenziswa Laser wokugubha umshini kanye neminye imishini laser. 
    Yizinto kuphela eziqinile ezingasebenza ngokuqhubekayo ekamelweni lokushisa, futhi iyikristal ye-laser esebenza kahle kakhulu.
    Futhi, i-laser ye-YAG (yttrium aluminium garnet) ingafakwa i-chromium neodymium ukuze ithuthukise izici zokumunca i-laser.I-Nd, Cr: i-laser ye-YAG iyi-laser yesimo esiqinile.I-Chromium ion (Cr3 +) inokumunca okubanzi ibhendi; ithatha amandla futhi iwadlulisele kuma-neodymium ions (Nd3 +) ngendlela yokusebenzisana kwe-dipole-dipole.I-Wavelength ye-1064nm ikhishwa yile laser.
    Isenzo se-laser se-Nd: YAG laser siboniswe okokuqala eBell Laboratories ngonyaka we-1964 I-Nd, Cr: i-laser ye-YAG ifuthwa ngemisebe yelanga.Ngokusebenzisa i-chromium, amandla wokumunca amandla we-laser ayathuthukiswa futhi Ama-pulses amafushane kakhulu akhishwa.
