I-Nd: Induku ye-crystal ye-YAG isetshenziswa emshinini wokumaka we-Laser neminye imishini ye-laser.
Iwukuphela kwezinto eziqinile ezingasebenza ngokuqhubekayo ekamelweni lokushisa, futhi iyikristalu ye-laser esebenza kahle kakhulu.
Futhi, i-laser ye-YAG (yttrium aluminium garnet) ingafakwa nge-chromium ne-neodymium ukuze kuthuthukiswe izici zokumunca ze-laser.I-laser ye-Nd,Cr:YAG iyi-laser yesimo esiqinile.I-Chromium ion(Cr3+) inokumuncwa okubanzi ibhande;imunca amandla futhi iwadlulisele kumayoni e-neodymium(Nd3+) ngendlela yokusebenzisana kwe-dipole-dipole.Ubude begagasi obungu-1064nm bukhishwa yile laser.
Isenzo se-laser ye-Nd:YAG laser yaboniswa okokuqala e-Bell Laboratories ngonyaka ka-1964. I-Nd, Cr:YAG laser impontshwa ngemisebe yelanga. Ngokusebenzisa i-chromium, umthamo wokumunca amandla we-laser uyathuthukiswa futhi ama-ultra short pulses ayakhishwa.
