Zinthu zogwira ntchito kuchokera ku makristasi a Erbium doped Yttrium Scandium Gallium Garnet (Er:Y3Sc2Ga3012 kapena Er:YSGG), makhiristo amodzi, amapangidwa kuti apange ma lasers opopa olimba omwe amawala mumtunda wa 3 µm.Makristalo a Er:YSGG amawonetsa momwe amagwirira ntchito limodzi ndi makristalo a Er:YAG, Er:GGG ndi Er:YLF omwe amagwiritsidwa ntchito kwambiri.
Nyali yonyezimira imapopedwa ma laser olimba otengera Cr,Nd ndi Cr,Er doped Yttrium Scandium Gallium Garnet makhiristo (Cr,Nd:Y3Sc2Ga3012 kapena Cr,Nd:YSGG ndi Cr,Er:Y3Sc2Ga3012 kapena Cr,Er:YSGG) ali ndi apamwamba kwambiri magwiridwe antchito kuposa omwe adachokera pa Nd:YAG ndi Er:YAG.Zinthu zogwira ntchito zopangidwa kuchokera ku makhiristo a YSGG ndizabwino kwambiri kwa ma lasers apakati amphamvu ndi kubwereza kobwereza mpaka makumi angapo.Ubwino wa makhiristo a YSGG poyerekeza ndi makhiristo a YAG amatayika pamene zinthu zazikuluzikulu zimagwiritsidwa ntchito chifukwa cha kutentha kwa makristalo a YSGG.
