Nd: YAG crystal sanda ake amfani da Laser marking inji da sauran Laser kayan aiki.
Shi ne kawai m abubuwa da za su iya ci gaba da aiki a dakin zafin jiki, kuma shi ne mafi kyau kwarai yi Laser crystal.
Har ila yau, ana iya yin amfani da laser YAG (yttrium aluminum garnet) tare da chromium da neodymium don haɓaka halayen shayarwa na laser.Nd, Cr: YAG Laser shine laser mai ƙarfi. Chromium ion (Cr3+) yana da babban sha. band;yana ɗaukar makamashi kuma yana canja shi zuwa ions neodymium (Nd3+) ta hanyar haɗin gwiwar dipole-dipole. Tsawon tsayin 1064nm yana fitar da wannan laser.
The Laser mataki na Nd: YAG Laser aka farko nuna a Bell Laboratories a cikin shekara ta 1964. The Nd, Cr: YAG Laser da aka pumped da hasken rana radiation.By doping da chromium, da makamashi sha iya aiki na Laser da aka inganta kuma ultra gajeriyar bugun jini suna fitarwa.
