    Xuduudaha farsamada

    Erbium iyo ytterbium co-doped phosphate galaas ayaa leh codsi ballaadhan sababtoo ah sifooyinka wanaagsan.Inta badan, waa qalabka ugu fiican muraayadda 1.54μm laser ay sabab u tahay mawjada badbaadada isha ee 1540 nm iyo gudbinta sare ee jawiga.Waxa kale oo ay ku habboon tahay codsiyada caafimaadka halkaasoo baahida ilaalinta indhaha ay ku adkaan karto in la maareeyo ama la yareeyo ama la joojiyo indho-indheynta aragga ee muhiimka ah.Dhowaan waxa loo istcimaali jiray isgaadhsiinta fiber indhaha halkii EDFA lagu daray aad u badan.Horumar weyn ayaa dhankan laga gaaray.
    Muraayadaha Erbium oo lagu dhejiyay Er 3+ iyo Yb 3+ oo ku habboon codsiyada ku lug leh heerarka soo noqnoqda ee sarreeya (1 - 6 Hz) oo lagu shubay 1535 nm laser diodes.Muraayaddan waxaa lagu heli karaa heerar sare oo Erbium ah (ilaa 1.7%).
    Muraayadaha Erbium oo lagu dhejiyay Er 3+, Yb 3+ iyo Cr 3+ oo ku habboon codsiyada ku lug leh bamgareynta nalka xenon.Muraayaddan waxaa inta badan loo adeegsadaa codsiyada kala duwan ee laysarka (LRF).
