Nd: A na-eji mkpanaka kristal YAG na igwe akara akara Laser na akụrụngwa laser ndị ọzọ.
Ọ bụ naanị ihe siri ike nwere ike ịrụ ọrụ na-aga n'ihu na ụlọ okpomọkụ, yana kristal laser kachasị mma.
Ọzọkwa, laser YAG (yttrium aluminum garnet) nwere ike doped na chromium na neodymium iji welie njirimara absorption nke laser. Nd, Cr: YAG laser bụ laser steeti siri ike.Chromium ion (Cr3+) nwere nnukwu absorption. ìgwè;ọ na-amịkọrọ ike ma na-ebufe ya na neodymium ions (Nd3 +) site na mmekọrịta dipole-dipole. Ogologo ogologo nke 1064nm na-apụta site na laser a.
The laser edinam nke Nd: YAG laser e mbụ gosiri na Bell Laboratories n'afọ 1964. The Nd, Cr: YAG laser na-pumped site a anyanwụ radieshon.By doping na chromium, na ike absorption ikike nke laser na-enwekwukwa na. ultra mkpụmkpụ usu na-ekupụta.
