laser fiber e sebetsa joang?–Lisa ea tsoang fekthering ea ho itšeha ka laser ea Ruijie
Fiber e sebelisoang e le setsi sa bohareng bakeng sa laser ea hau e tla be e entsoe ka lintho tse sa tloaelehang tsa lefatše, 'me hangata u tla fumana hore ena ke Erbium.Lebaka leo sena se etsoang ke hobane maemo a athomo a likarolo tsena tsa lefats'e a na le matla a bohlokoa haholo, a lumellang hore ho sebelisoe mohloli o theko e tlaase oa pompo ea diode laser, empa seo se ntse se tla fana ka tlhahiso e phahameng ea matla.
Mohlala, ka faeba ea doping ho Erbium, boemo ba matla bo ka monyang li-photon ka bolelele ba 980nm bo senyeha ho ba meta-stable e lekanang le 1550nm.Se boleloang ke sena ke hore o ka sebelisa mohloli oa pompo ea laser ho 980nm, empa o ntse o fihlela boleng bo holimo, matla a phahameng le beam ea laser ea matla a 1550nm.
Liathomo tsa Erbium li sebetsa joalo ka laser medium ka har'a faeba ea doped, 'me li-photon tse hlahisoang li lula ka har'a fiber core.Ho theha sekoti seo lifoto li lulang li koaletsoe ho sona, ho eketsoa ntho e tsejoang e le Fiber Bragg Grating.
Bragg Grating ke feela karolo ea khalase e nang le mela ka hare ho eona - e leng moo index ea refractive e fetotsoeng.Nako le nako ha leseli leo le tšela moeli pakeng tsa index e le 'ngoe ea refractive le e latelang, leseli le lenyenyane le khutlisetsoa morao.Ha e le hantle, Bragg Grating e etsa hore laser ea fiber e sebetse joalo ka seipone.
Laser ea pompo e tsepamisitsoe ho cladding e lutseng ho potoloha fiber core, kaha fiber core ka boeona e nyane haholo hore e ka ba le laser diode ea boleng bo tlase e tsepamisitsoeng ho eona.Ka ho pompa laser ka har'a sekoaelo se pota-potileng mokokotlo, laser e phunyeletsoa ka hare, 'me nako le nako ha e feta bohareng, leseli le eketsehileng la pompo le kenngoa ke mantlha.
