Sebopeho sa sistimi ea laser ea fiber e matla haholo
1, Sebopeho sa sistimi
Laser ea fiber e matla haholo e na le likarolo tse 'ne: mohloli oa pompo, motsoako oa pompo, fiber ea gain, le hlooho ea tlhahiso ea laser.
1.1 Mohloli oa pompo: Matla a tlhahiso ea die e le 'ngoe ea laser ke 10W ~ 50W feela, 'me die tse 6 ~ 50 li tla kopanngoa le ho pakoa ho latela tlhoko; Haeba ho na le palo e kholo ea li-chip, ho kopanya mahlaseli a sebaka le ho kopanya mahlaseli a polarization ho tla kopanngoa ho eketsa matla. Matla a mohloli o le mong oa pompo a tloha ho mashome ho isa ho makholo a li-watt, 'me ho fihlela tlhahiso ea boemo ba kilowatt, mehloli e fetang 10 ea pompo e hloka ho hokeloa ka tatellano (joalo ka laser ea Ruike e sebelisang motsoako oa mehloli e 11 ea pompo).
1.2 Motsoako oa pompo: E hlahisitsoe ka theknoloji ea ho kopanya fiber fusion, li-module tse ngata tsa pompo li kopantsoe ka optically ho ba fiber e le 'ngoe.
1.3 Faeba e fumanwang: ka bolelele bo atisang ho feta dimithara tse 30, e tla kobeha mme e bewe hodima poleiti ya ho qhala mocheso, hangata ho sebediswa sebopeho sa ytterbium doped double cladding: bophara ba mantlha ba 10-20 μ m, waveguide ya mokgwa o le mong/few, e kentsweng ka di-ion tsa ytterbium; Bophara ba ka hare ba cladding bo fihla ho 400 μ m mme bo sebedisetswa ho fetisa lesedi la pompo ya mekgwa e mengata.
1.4 Hlooho ea Tlhahiso ea Laser: E ikarabella bakeng sa tlhahiso ea ho qetela ea laser 'me e ka hokahanngoa le lisebelisoa tsa ts'ebetso ka sebopeho se tloaelehileng.
2, Molao-motheo oa mantlha oa ho sebetsa
2.1 Resonator bakeng sa ho holisa mahlo: e entsoe ka para ea li-grating tsa Bragg (FBGs): grating e phahameng ea ho bonahatsa khanya (reflectivity>99%) e bonahatsa khanya ea bolelele ba leqhubu bo reriloeng (joalo ka 1080nm) ho khutlela ho fiber e hahang; Grating e kopantsoeng ea tlhahiso (reflectivity 10% ~ 50%) e bonahatsa hanyane ho boloka ho sisinyeha, 'me e fetisetsa hanyane ho theha tlhahiso. Leseli la pompo le hlohlelletsa li-ion tsa ytterbium ho hlahisa mosi o sa reroang, 'me li-photon tse fihlelang litlhoko tsa bolelele ba leqhubu li holisoa khafetsa lipakeng tsa li-grating, qetellong li etsa tlhahiso e tsitsitseng ea laser.
2.2 Kgetho ya Mokgwa e netefatsa boleng ba mahlasedi: Ka lehlakoreng le leng, ho itshetlehile ka moedi wa waveguide wa lera le lenyenyane la motheo la bophara, phetiso e tlase feela ya tahlehelo ya mokgwa wa motheo e dumellwa; Ka lehlakoreng le leng, ka ho sebedisa ho kopana ho hoholo pakeng tsa mokgwa wa motheo le gain medium (ytterbium ions), hammoho le dibopeho tse hodimo tsa tahlehelo ya mokgwa wa maemo a hodimo, hammoho le moralo wa ho kobeha ha faeba ho sefa ka ho eketsehileng mekgwa ya maemo a hodimo, tlhahiso ya mokgwa wa motheo wa boleng bo hodimo e nang le M² e atamelang 1 qetellong e fihlellwa.
