Nd YAG
Waxa la alifay lixdamaadkii qarnigii hore, Nd:YAG waxa ay ahayd oo sii wadaysaa in ay noqoto crystal-ka ugu isticmaalka badan ee loo isticmaalo walxaha crystal-state adag.Xarumaheeda laysarka ayaa ah tanaasul wanaagsan oo u dhexeeya meelaha ay ku wanaagsan tahay iyo meelaha ay ku liidato ee tartankeeda.Nd: YAG crystals waxaa loo isticmaalaa dhammaan noocyada lasers-state adag.Marka la barbar dhigo kiristaalo laysarka kale, cimrigiisa fluorescence waa laba jeer ka badan Nd:YVO4 , iyo conductivity kaamerada sidoo kale waa ka wanaagsan yahay.
Tilmaamaha iyo Codsiyada
