    Nd: YAG siv lead ua pas nrig yog siv hauv Laser npav tshuab thiab lwm yam khoom siv laser.
    Nws yog tib yam khoom uas tuaj yeem ua haujlwm tsis tu ncua ntawm chav tsev kub, thiab yog qhov 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 txhawm rau txhim kho qhov nqus cov yam ntxwv ntawm lub laser.The Nd, Cr: YAG laser yog lub xeev ruaj khov laser.Chromium ion (Cr3+) muaj qhov dav dav. band;nws absorbs lub zog thiab hloov nws mus rau lub neodymium ions (Nd3 +) los ntawm txoj kev ntawm dipole-dipole interactions.Wavelength ntawm 1064nm yog emitted los ntawm no laser.
    Lub laser txiav ntawm Nd:YAG laser yog thawj zaug pom nyob rau hauv Tswb Laboratories nyob rau hauv lub xyoo 1964.The Nd, Cr:YAG laser yog pumped los ntawm lub hnub ci hluav taws xob.By doping nrog chromium, lub zog nqus peev xwm ntawm lub laser yog txhim khu kev qha thiab ultra luv pulses yog emitted.
