    Nd: YAG siv lead ua cov pas nrig yog siv hauv Laser npav tshuab thiab lwm yam khoom siv laser. 
    Nws yog tib cov khoom sib tw uas tuaj yeem ua haujlwm tsis tu ncua ntawm chav sov, thiab yog kev ua tau zoo tshaj plaws laser siv lead ua.
    Tsis tas li ntawd, YAG (yttrium aluminium garnet) laser tuaj yeem doped nrog chromium thiab neodymium thiaj li yuav txhim kho cov yam ntxwv ntawm lub laser.Lub Nd, Cr: YAG laser yog lub xeev lub xeev laser ..Chromium ion (Cr3 +) muaj qhov siab dav pawg; nws nqus lub zog thiab hloov nws mus rau lub neodymium ions (Nd3 +) los ntawm txoj kev dipole-dipole kev sib cuam tshuam.Wavelength ntawm 1064nm tawm ntawm lub tshuab hluav taws xob no.
    Qhov kev txiav txim siab ntawm Nd: YAG laser tau ua kom pom thawj zaug ntawm Tswb Chaw Tshawb Fawb hauv xyoo 1964.Qhov Nd, Cr: YAG laser tau nqus los ntawm lub hnub ci hluav taws xob.By doping nrog chromium, lub zog nqus tau lub zog ntawm lub laser yog txhim kho thiab ultra luv luv pulses yog emitted.
