    Kev tsis

    Erbium thiab ytterbium co-doped phosphate iav muaj daim ntawv thov dav vim tias muaj cov khoom zoo. Feem ntau, nws yog cov khoom siv iav zoo tshaj plaws rau 1.54μm laser vim nws qhov muag muaj kev nyab xeeb ntawm 1540 nm thiab lub siab kis tau los ntawm cov cua. Nws tseem tsim nyog rau kev siv kho mob qhov uas xav tau kev tiv thaiv qhov muag yuav nyuaj rau kev tswj hwm lossis ploj zuj zus lossis cuam tshuam qhov muag pom. Tsis ntev los no nws tau siv nyob rau hauv kev sib txuas lus fiber ntau hloov ntawm EDFA rau nws qhov ntau tshaj. Muaj kev kawm tau zoo nyob hauv daim teb no.
    Erbium iav doped nrog Er 3+ thiab Yb 3+ thiab haum rau cov ntawv thov muaj feem rov ua dua tus nqi (1 - 6 Hz) thiab tau tso nrog 1535 nm laser diodes. Cov iav no muaj qhov siab ntawm Erbium (nce txog 1.7%).
    Erbium iav doped nrog Er 3+, Yb 3+ thiab Cr 3+ thiab haum rau cov ntawv thov cuam tshuam nrog xenon lub teeb nyem. Cov iav no feem ntau siv rau hauv laser ntau cov kev pom (LRF) kev siv.
