Xyoo 1843, Mossander ntawm Sweden pom lub ntsiab erbium. Cov khoom siv kho tshiab ntawm pawg neeg yog qhov tseem ceeb, thiab lub teeb pom kev zoo, muaj qhov tseem ceeb tshaj plaws ntawm qhov ntsuas hluav taws xob qis tshaj plaws ntawm cov kev sib txuas lus fiber ntau.Hoob laugions (Er *) yog zoo siab los ntawm lub teeb ntawm wavelengths ntawm 880mm, thiab kev hloov pauv ntawm lub xeev teeb tsa 415/2 rau lub xeev kev lag luam 213/2. Thaum ER * hauv kev hloov pauv lub zog hauv av rov qab mus rau hauv av lub xeev, nws emits 1550mm wavelength ci tuaj yeem xa ntau yam wavelengths ntawm lub teeb sib txawv. Lub khoos phis tawm kho qhov muag nrog 1550mm zaus network muaj lub sijhawm qis tshaj tawm lub sijhawm hauv quartz kho kho qhov muag (O. 15A1 / Krm), yuav luag txog qhov qis ntawm cov duab.
(1) Yog li no, thaum muaj fiber kev sib txuas lus yog siv raws li teeb liab teeb ntawm 1550mm, qhov kev poob zoo yog qhov tsawg. Nyob rau hauv txoj kev no, yog tias txoj kab kev haum tsis muaj doping yog siv rau kev sib txuas lus, lub amplifier tuaj yeem ua raws li lub ntsiab cai ntawm laser. Yog li ntawd, hauv kev sib tham xov tooj uas yuav tsum tau tshaj tawm nthwv cua 1550mm / Kho dua tshiab teeb liab, Weenical teeb liab, kab nuv ntses fiber ntau dua. Tam sim no, doped Silica Fiber AmloundInience tau ua lag luam. Raws li cov lus tshaj tawm, txhawm rau zam kev nqus tsis zoo, cov khoom siv doping ntau ntawm cov roj fiber yog kaum mus rau ntau pua tus ppm (LPPM-10-.). Kev loj hlob sai ntawm kev sib txuas lus fiber ntau yuav qhib tau cov teb tshiab rau cov ntawv thov ntawm pawg.
(2) Ntxiv rau, tus bait laser crystal thiab nws cov txiaj ntsig, muaj peev xwm tsis pub lwm tus paub, muaj qhov sib txawv ntawm cov yeeb ncuab, tsis muaj peev xwm siv tau yooj yim rau tib neeg, tsis muaj peev xwm siv tau yooj yim rau tib neeg, tsis muaj peev xwm siv tau yooj yim rau tib neeg, tsis muaj peev xwm siv tau yooj yim rau tib neeg lub hlwb, thiab muaj lub zog zoo rau kev nkag rau hauv cov yeeb ncuab, thiab muaj kev sib txawv ntawm cov tub rog istumbating tub rog istuminating. Lawv tau ua rau cov laser laser Portable rau kev siv tub rog, uas muaj kev nyab xeeb rau tib neeg lub qhov muag.
(3) BP + tuaj yeem ntxiv rau lub khob kom tsis txhob muaj lub ntiaj teb laser, uas tam sim no muaj cov khoom siv roj ntau tshaj plaws thiab tso zis zog.
(4) EP + kuj tseem siv tau los ua kev ua kom ion rau kev hloov cov ntaub ntawv laser laser.
(5) Tsis tas li ntawd, cov kab mob uas tseem tuaj yeem siv rau kev txiav tawm kom zoo nkauj thiab xim ntawm cov iav iav ci ntsa iab thiab crystalline.
