    Technical parameter

    Erbium uye ytterbium co-doped phosphate girazi rine rakapamhamha application nekuda kwezvakanakisa zvivakwa. Kunyanya, ndiyo yakanakisa girazi zvinhu zve 1.54μm laser nekuda kweziso rayo rakachengeteka wavelength ye1540 nm uye yakakwira kufambisa kuburikidza nemhepo. Izvo zvakare zvinokodzera kunyorera zvekurapa uko kudiwa kwekuchengetedzwa kwemaziso kungave kwakaoma kubata kana kudzikisira kana kudzivisa kutarisisa kwakakosha kwekuona. Munguva pfupi yapfuura inoshandiswa mukutaurirana kwefiber fiber pachinzvimbo cheEDFA kune yayo yakawanda yepamusoro. Pane kufambira mberi kukuru mundima iyi.
    Erbium Girazi rakaiswa neEre 3+ uye Yb 3+ uye inokodzera kunyorera kunosanganisira kudzokorora kwakakwira mitengo (1 - 6 Hz) uye kupombwa ne1535 nm laser diode. Iri girazi rinowanikwa nematanho epamusoro eErbium (anosvika 1.7%).
    Erbium Girazi rakaiswa neEr 3+, Yb 3+ uye Cr 3+ uye inokodzera kunyorera kunosanganisira xenon mwenje kupomba. Iri girazi rinowanzo shandiswa mumashandisirwo e laser range finder (LRF).
