Ho, Cr, Tm: YAG -yttrium aluminium garnet crystals laser doped with chromium, thulium iyo ions holium si ay u bixiyaan lasing at 2.13 microns ayaa helaya codsiyo badan iyo dheeraad ah, gaar ahaan in industry ee caafimaadka. Faa'iidada dabiiciga ah ee crystal crystal waa in ay waxay shaqaaleysiisaa YAG martigeliyaha.YAG jirkeeda, kulaylka iyo sifooyinka indhaha ayaa si fiican loo yaqaan oo ay fahmaan nashqadeeyaha laser kasta.Waxay leedahay codsiyo ballaadhan oo xagga qalliinka, dhakhtarka ilkaha, baaritaanka jawiga, iwm.
