Kapangidwe ka dongosolo la laser yamphamvu kwambiri
1, kapangidwe ka dongosolo
Laser yamphamvu kwambiri ya fiber ili ndi magawo anayi: gwero la pampu, chophatikiza cha pampu, fiber yopeza, ndi mutu wotulutsa wa laser.
1.1 Gwero la Pampu: Mphamvu yotulutsa ya die imodzi ya laser ndi 10W ~ 50W yokha, ndipo ma die 6 ~ 50 adzaphatikizidwa ndikupakidwa malinga ndi kufunikira; Ngati pali ma chip ambiri, kuphatikiza kwa beam ndi polarization beam combination zidzaphatikizidwa kuti ziwonjezere mphamvu. Mphamvu ya gwero limodzi la pampu imayambira pa ma watts makumi mpaka mazana, ndipo kuti pakhale kuchuluka kwa kilowatt, magwero opitilira 10 a pampu ayenera kulumikizidwa motsatizana (monga laser ya Ruike pogwiritsa ntchito kuphatikiza kwa magwero 11 a pampu).
1.2 Chosakaniza mapampu: Chopangidwa kudzera muukadaulo wa fiber fusion splicing, ma module angapo apampu amalumikizidwa modabwitsa kukhala ulusi womwewo.
1.3 Ulusi wowonjezera: wokhala ndi kutalika kopitilira mamita 30, udzakulungidwa ndikukhazikika pa mbale yotenthetsera kutentha, nthawi zambiri pogwiritsa ntchito kapangidwe ka ytterbium doped double cladding: core diameter ya 10-20 μ m, single mode/few mode waveguide, wopakidwa ndi ytterbium ions; M'mimba mwake wamkati wa cladding umafika 400 μ m ndipo umagwiritsidwa ntchito potumiza kuwala kwa pampu ya multi-mode.
1.4 Mutu Wotulutsa Laser: Uli ndi udindo pa kutulutsa komaliza kwa laser ndipo ukhoza kulumikizidwa ku zida zogwirira ntchito kudzera mu mawonekedwe wamba.
2, mfundo yogwirira ntchito yapakati
2.1 Resonator yopangira kuwala: yopangidwa ndi ulusi wa Bragg gratings (FBGs): grating yowunikira kwambiri (reflectivity>99%) imawonetsa kuwala kwa kutalika kwa mafunde komwe kumayang'aniridwa (monga 1080nm) kubwerera ku ulusi wopeza; Grating yolumikizidwa yotulutsa (reflectivity 10% ~ 50%) imawonetsa pang'ono kuti isunge kugwedezeka, ndipo imatumiza pang'ono kuti ipange kutulutsa. Kuwala kwa pampu kumasangalatsa ma ioni a ytterbium kuti apange kutulutsa kodzidzimutsa, ndipo ma photon omwe amakwaniritsa zofunikira za kutalika kwa mafunde amakulitsidwa mobwerezabwereza pakati pa gratings, pamapeto pake amapanga kutulutsa kokhazikika kwa laser.
2.2 Kusankha njira kumaonetsetsa kuti kuwala kwa kuwala kuli bwino: Kumbali imodzi, kudalira malire a waveguide a core layer yaying'ono, kutumiza kochepa kwa njira yoyambira kumaloledwa; Kumbali inayi, pogwiritsa ntchito kufalikira kwakukulu pakati pa njira yoyambira ndi njira yopezera (ytterbium ions), komanso mawonekedwe otayika kwambiri a njira zoyambira, kuphatikiza kapangidwe ka fiber bending kuti apitirize kusefa njira zoyambira zapamwamba, kutulutsa kwapamwamba kwambiri kwa njira yoyambira yokhala ndi M² ikuyandikira 1 pamapeto pake kumakwaniritsidwa.
