    Nd: YAG kristale molamu e sebelisoa ka Laser tšoaea mochini le lisebelisoa tse ling tsa laser. 
    Ke tsona feela lintho tse tiileng tse ka sebetsang ka ho tsoelang pele mocheso oa mohatsela, 'me ke kristale ea laser e sebetsang hantle haholo.
    Hape, laser ea YAG (yttrium aluminium garnet) e ka etsoa doped ka chromium le neodymium molemong oa ho ntlafatsa litšobotsi tsa ho noa ha laser. Nd, Kr: laser ea YAG ke laser ea mmuso e tiileng. sehlopha; e monya matla le ho e fetisetsa ho li-ion tsa neodymium (Nd3 +) ka tsela ea litšebelisano tsa dipole-dipole. Bolelele ba 1064nm bo hlahisoa ke laser ena.
