Takulandilani ku Ruijie Laser

Kodi fiber laser imagwira ntchito bwanji? -Lisa waku Ruijie fiber laser kudula fakitale

Ulusi womwe umagwiritsidwa ntchito ngati sing'anga yapakati pa laser yanu ukhala utayikidwa muzinthu zapadziko lapansi, ndipo nthawi zambiri mumapeza kuti iyi ndi Erbium.Chifukwa chomwe izi zimachitikira chifukwa ma atomu a zinthu zapadziko lapansi ali ndi mphamvu zothandiza kwambiri, zomwe zimalola kuti pampu ya laser ya diode igwiritsidwe ntchito, koma izi ziperekabe mphamvu zambiri.

Mwachitsanzo, ndi doping fiber ku Erbium, mphamvu yomwe imatha kuyamwa ma photon okhala ndi kutalika kwa 980nm imavunda mpaka meta-stable yofanana ndi 1550nm.Izi zikutanthauza kuti mutha kugwiritsa ntchito gwero la mpope la laser pa 980nm, komabe mukwaniritse mtengo wapamwamba kwambiri, mphamvu yayikulu komanso mtengo wapamwamba wa laser wa 1550nm.

Ma atomu a Erbium amakhala ngati sing'anga ya laser mu ulusi wa doped, ndipo ma photons omwe amatulutsidwa amakhalabe mkati mwa fiber core.Kuti apange chibowo chomwe mafotoni amakhalabe otsekeredwa, chinthu chodziwika kuti Fiber Bragg Grating chimawonjezedwa.

Bragg Grating ndi gawo chabe lagalasi lomwe lili ndi mikwingwirima mkati mwake - pomwe mlozera wa refractive wasinthidwa.Nthawi iliyonse kuwalako kukadutsa malire pakati pa cholozera chimodzi cha refractive ndi china, kuwala kwakung'ono kumabwereranso.Kwenikweni, Bragg Grating imapangitsa fiber laser kukhala ngati galasi.

Laser yapampu imayang'ana kwambiri pazovala zomwe zimakhala mozungulira pachimake cha fiber, popeza nsonga yake ndiyochepa kwambiri kuti ikhale ndi laser ya diode yotsika kwambiri.Popopera laser muzitsulo zozungulira pachimake, laser imawombera mkati, ndipo nthawi iliyonse ikadutsa pachimake, kuwala kwapampu kumatengedwa ndi pachimake.
