Nd, :R: YAG kristal

YAG (yttrium aluminum garnet) laser nwere ike doped na chromium na neodymium iji mee ka absorption àgwà nke laser. NdCrYAG laser bụ steeti steeti siri ike. Chromium ion (Cr3 +) nwere a sara mbara absorption gbalaga; ọ na-amịkọrọ ume ma bufee ya na ion neodymium (Nd3 +) site na ụzọ mmekọrịta dipole-dipole. A na-ebugharị ntụgharị nke 1.064 µm nke laser a.
Emere laser nke Nd-YAG laser na Bell Laboratories n'afọ 1964. A na-agba laser laser NdCrYAG site na radieshon nke anyanwụ. Site na doping na chromium, a na-emezi ike itinye ume nke laser na obere mkpụmkpụ mkpụmkpụ.
Ahụkarị ngwa nke a laser gụnyere mmepụta nke nanopowders na dị ka a pumping isi iyi nke ọzọ lasers. 
Ngwa:
Isi ngwa nke Nd: Cr: YAG laser dị ka isi iyi mgbapụta. A na-eji ya na lasers pumped lasers, nke a ga-eji dị ka sistemụ dị na mbara igwe.
Ngwa ọzọ nke Nd: CrR: YAG laser dị na nnwale nke nanopowder.
