Ndi YAG
Yopangidwa m'zaka za m'ma sikisite yazaka zapitazi, Nd:YAG yakhala ndipo ikupitilizabe kugwiritsidwa ntchito kwambiri pamitundu yolimba ya kristalo.Magawo ake a laser ndikugwirizana bwino pakati pa mphamvu ndi zofooka za mpikisano wake.Nd: makhiristo a YAG amagwiritsidwa ntchito pamitundu yonse ya ma laser olimba.Poyerekeza ndi makhiristo ena a laser, nthawi yake ya fluorescence imakhala yowirikiza kawiri kuposa Nd:YVO4, komanso matenthedwe amafuta ndi abwinoko.
