Erbium thiab ytterbium co-doped phosphate iav muaj daim ntawv thov dav vim yog cov khoom zoo heev.Feem ntau, nws yog cov khoom siv iav zoo tshaj plaws rau 1.54μm laser vim nws qhov muag nyab xeeb wavelength ntawm 1540 nm thiab siab kis tau los ntawm huab cua.Nws kuj tseem tsim nyog rau daim ntawv thov kev kho mob uas xav tau kev tiv thaiv qhov muag yuav nyuaj los tswj lossis txo qis lossis cuam tshuam qhov tseem ceeb ntawm kev pom.Tsis ntev los no nws tau siv nyob rau hauv kev sib txuas lus kho qhov muag fiber ntau es tsis txhob EDFA rau nws cov super plus.Muaj kev vam meej hauv daim teb no.
Erbium iav doped nrog Er 3+ thiab Yb 3+ thiab haum rau cov ntawv thov uas muaj qhov rov ua dua siab dua (1 - 6 Hz) thiab tau nqus nrog 1535 nm laser diodes.Cov iav no muaj nyob nrog qib siab ntawm Erbium (txog 1.7%).
Erbium iav doped nrog Er 3+, Yb 3+ thiab Cr 3+ thiab haum rau cov ntawv thov uas muaj xenon teeb siv.Cov iav no feem ntau siv rau hauv daim ntawv thov laser range finder (LRF).
