Er:Galasi - Yopangidwa Ndi 1535 Nm Laser Diodes
Mafotokozedwe Akatundu
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.
EAT14 ndi 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%).
Cr14 ndi Erbium Glass yopangidwa ndi Er 3+, Yb 3+ ndi Cr 3+ ndipo imayenera kugwiritsa ntchito makina opopa nyali a xenon. Galasi iyi imagwiritsidwa ntchito nthawi zambiri pamapulogalamu a laser rangefinder (LRF).
Tilinso ndi mtundu wosiyana wa Er: galasi, monga wofiirira, wobiriwira, ndi zina zotero. Mutha kusintha mawonekedwe ake onse. Ndipatseni magawo enieni kapena zojambulazo ndi zabwino kuti injiniya wathu aweruze.
