CTH: Likristale tsa YAG

Ho,Cr,Tm:YAG -yttrium aluminium garnet laser crystals e entsoeng ka chromium,thulium le holmium ions ho fana ka lasing ho 2.13 microns li fumana lisebelisoa tse ngata, haholo-holo indastering ea bongaka.Molemo oa tlhaho oa kristale ke hore e sebelisa YAG joalo ka moamoheli.Lintho tsa 'mele, tsa mocheso le tsa mahlo tsa YAG li tsebahala ebile li utloisisoa ke moetsi e mong le e mong oa laser.E na le ts'ebeliso e pharaletseng ho opereishene, bongaka ba meno, tlhahlobo ea sepakapaka, jj.
