Erbium ndi ytterbium co-doped phosphate galasi ali ndi ntchito yotakata chifukwa cha zinthu zabwino kwambiri.Nthawi zambiri, ndigalasi yabwino kwambiri ya 1.54μm laser chifukwa cha kutalika kwake kwamaso kwa 1540 nm komanso kufalikira kwakukulu mumlengalenga.Ndiwoyeneranso kuchipatala komwe kufunikira koteteza maso kungakhale kovuta kuwongolera kapena kuchepetsa kapena kulepheretsa kuyang'ana kofunikira.Posachedwapa amagwiritsidwa ntchito mu optical fiber communication m'malo mwa EDFA chifukwa chapamwamba kwambiri.Pali kupita patsogolo kwakukulu pankhaniyi.
Erbium Glass yopangidwa ndi Er 3+ ndi Yb 3+ ndipo imagwirizana ndi mapulogalamu obwerezabwereza (1 - 6 Hz) ndi kupopa ndi 1535 nm laser diode.Galasi ili limapezeka ndi Erbium yapamwamba (mpaka 1.7%).
Erbium Glass yodzaza ndi Er 3+, Yb 3+ ndi Cr 3+ ndipo imagwirizana ndi kugwiritsa ntchito kupopera nyale kwa xenon.Galasi iyi imagwiritsidwa ntchito nthawi zambiri pamapulogalamu a laser rangefinder (LRF).
